Signal Processing Jobs

I am building a full-path DVB-T2 physical-layer simulation in MATLAB / Simulink and need a clean, well-documented model that demonstrates Adaptive Modulation and Coding using Quadrature Amplitude Modulation. The core emphasis is on the modulation scheme itself rather than error-control blocks or post-detection processing, so the model should let me vary constellation orders (e.g., 16-QAM, 64-QAM, 256-QAM) and observe the impact on throughput and BER under different channel conditions. Key elements I need: • A runnable Simulink (.slx) file that instantiates the complete DVB-T2 baseband chain up to the QAM mapper, includes channel impairment blocks (AWGN, fading), and ends with demodulation so I can plot BER and EVM. • Parameter masks or scripts that let me switch constellation...

I need a matched RF transmitter-receiver pair engineered from the ground up for remote control operation. When the handheld transmitter is activated, the receiver must recognise a unique code and immediately trigger a defined sequence of actions inside my host device. Reliability, low latency and immunity to casual interference are essential. Here’s what I’m expecting from you: • Schematic and PCB layout for both transmitter and receiver, ready for fabrication. • PCB Gerber files. • Breadboard demonstrating functionality. • Firmware (or discrete logic plan) that decodes the signal and drives the action sequence pins • A succinct test report proving range, stability, and correct execution of the sequence in a lab environment. You are free ...

I want to develop a LabVIEW VI that integrates and synchronizes data from two sources: an Arduino-controlled actuator and a DAQ-based voltage measurement system. The Arduino is responsible for controlling the motion of a stepper motor and continuously outputs position data over serial communication. Specifically, it transmits time and position in a comma-separated format as “time_ms, position_mm” at approximately 50 millisecond intervals. This output has already been verified to function correctly using the Arduino Serial Plotter which I wrote the code for. Also, a DAQ system within LabVIEW is used to measure the analog voltage output from a load cell. This voltage represents the sensor signal and does not need to be converted to force at this stage. The DAQ portion of the sys...

Low Power, High Speed,Area Efficient Multiplier based on the PTL logic style is the project title.I have to implement using cadence virtuoso gpdk090 nm technology and I want improvement of this paper for paper publishment.

I need a control-systems specialist to build a Model Predictive Controller for a wind turbine that I have already represented as a Linear Parameter-Varying (LPV) model in MATLAB/Simulink. The controller must juggle three objectives at once—maximising electrical power output, keeping mechanical stress to a minimum, and sharpening pitch-angle accuracy—while remaining robust to real-world disturbances such as wind-speed fluctuations, grid faults, and the occasional mechanical component hiccup. The core work happens in MATLAB/Simulink: setting up the prediction model, formulating the multi-objective cost function, and implementing hard or soft constraints that reflect turbine limits and grid-code requirements. I will provide the LPV model and any necessary operating data; you desi...

Design and Development of an Active Rectifier for Performance Enhancement of Induction Generator Based Wind Energy Conversion System

I need a complete engineering solution for an ultra-low-frequency electromagnetic transmitter that operates at roughly 22 Hz and fits inside an inline pipeline PIG. Once the PIG is in service, the beacon’s field must be strong enough to be detected up 3–5 m above the pipe, even when the signal has to pass through steel wall, backfill, soil, and asphalt or reinforced concrete. All operations take place underground and fully enclosed by steel, so coil geometry, core selection, drive strategy, and noise rejection are critical. Scope of Work: • Design a low-frequency (~15–30 Hz, target 22 Hz) EM transmitter • Optimize signal strength for underground detection • Develop efficient antenna/coil design suitable for pipeline use • Design low-power circuitry fo...

I need a small Python-based utility that runs reliably on macOS and strips the SyntID watermark Google bakes into both its Text-to-Music and Text-to-Speech outputs. The goal is simple: after processing, the resulting audio should pass Google’s own detection checks while sounding identical to the human ear. Here’s what matters most to me: • macOS compatibility out of the box (Monterey and newer) using standard Python 3 libraries plus any open-source audio packages you feel are essential. • One command (or callable function) that accepts a Google-generated audio file, cleans it, and writes back a high-fidelity file in the same format. • Clear inline comments and a concise README so I can understand the logic, install any dependencies with Homebrew/pip, and r...

I’m looking for an experienced engineer who can take my custom-built hardware and make it work seamlessly within a larger system. The heart of the job is hands-on hardware integration—not general project management—so I need someone who is comfortable troubleshooting boards, refining firmware, and confirming that every physical connection and signal behaves as intended. Key goals • Map out the integration plan for the custom boards, interfaces, and peripherals I already have on hand. • Develop or refine any required low-level firmware so the hardware communicates reliably with the host system. • Validate the full signal chain with bench testing, basic stress tests, and a succinct report of results. What I’ll provide – Schematics, compone...

I’m building a palm-sized device that helps automate at-home medication. Inside it sit two independent plungers driven by micro servos, a vibration motor, a small speaker for audio prompts, and a 1.68-inch colour display for on-device instructions and feedback. All of these elements need to live on a custom PCB, run from a single rechargeable battery that is properly sized for daily use, and work seamlessly together. You will receive the full parts kit, so your focus is on: • designing the board, • assembling and reflowing it, • loading the firmware, and • proving that everything operates exactly as intended. The most important interaction is tight, reliable coordination between the user’s button press (or other trigger you recommend) and the t...

Short Summary of the Research This research focuses on designing a high-gain antenna for 5G communication at 36–38 GHz (millimeter-wave). Since 5G at these frequencies suffers from high signal loss, the study aims to improve signal strength using an efficient antenna design. The proposed solution is a compact stacked slot antenna, which provides: Wide bandwidth (34–44 GHz) Stable radiation pattern (consistent signal in all directions) Minimum gain of ~6 dBi (higher in arrays) To improve performance, the antenna is developed in three stages: Single antenna element – basic design and testing 1×2 array – increases gain by ~2–3 dB 1×4 array – further improves gain (~6 dB increase overall) The study proves that increasing the number of antenna ele...

I have a LabVIEW program that is already developed and mostly complete. The cRIO hardware is also installed and configured in LabVIEW. The goal is to control one gas pump and one water pump using LabVIEW. Currently, the water pump is working properly, but the gas pump is not functioning. We need to identify the root cause of this issue. For this purpose, we are looking for a LabVIEW specialist who can help diagnose and resolve the problem. In addition, we have two sensors whose readings need to be displayed in LabVIEW. List of tasks to be completed on this nearly finished LabVIEW project: 1. Control the gas pump speed (increase/decrease) via LabVIEW commands 2. Ensure that the water pump, which is already functioning, is not disrupted 3. Connect two sensors to LabVIEW and display the...
