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