EE3: Real-Time Digital Signal Processing

Real-Time Digital Signal Processing on a Texas Instruments DSP Starter Kit (TMS320C6713 DSK). Imperial College London Electrical & Electronic Engineering 3rd year module.

Lab 5: IIR Filtering

Objectives accomplished:

  • Learned to design IIR (Infinite-Impulse Response) digital filters using MATLAB.
  • Implemented the IIR filter using the C6713 DSK system in real-time.
  • Measured the filter characteristics using a spectrum analyzer.

Project: Speech Enhancement through noise reduction

Telephones are increasingly being used in noisy environments such as cars, airports and undergraduate laboratories! The aim of this project is to implement a real-time system that will reduce the background noise in a speech signal while leaving the signal itself intact: this process is called speech enhancement.

~ Paul D. Mitcheson, Imperial College London Dept of EEE, EE3-19 Real Time Digital Signal Processing, 2016

Objectives accomplished:

  • Implemented triple buffering: in, processing, and out buffers.
  • Implemented various noise estimation and noise reduction techniques,
  • Compared their performance and chose parameters that produced the best audible speech enhancement.

Final Report.
