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.
