Wireless Digital Communication Training System

wicommt logo 200 The Ultimate Wireless Digital Communication Training System – SDR Platform

The Benchmark WiCOMM-T – the ultimate Wireless Digital Communication Traning System Platform – is the actual implementation of modern digital communication systems with direct interface to MATLAB through the Hi-Speed
USB port of a PC.


SDR software defined radio training

The WiCOMM-T is based on the curriculum developed in the Intel Wireless Laboratory of IIT Madras

The WiCOMM-T provides maximum flexibility in learning complete digital communication system concepts, which includes digital modulation techniques, Baseband Equalization, Filtering concepts, and the basics of CDMA, GSM etc. MATLAB codes of all suggested experiment topics are available to users as reference. A MATLAB interface to the Platform also allows users to try out other topics on their own.


Typical implementation of modern communication systems

Interface with MATLAB

  • Gives the ability to generate required signal and pass it through the transmitter and receiver providing a real life wireless digital communication system

Comprehensive manual – describes wide range of experiments

Loop back options at Baseband and at IF
