CDMA Mobile Communication Trainer Kit .
provides a basic understanding of the concepts behind CDMA, and
various issues that need to be considered in the design of a DSSS
system. It has digital modulation & demodulation along with direct
sequence spread spectrum (DSSS) generation and decoding, data signals,
zero random bit signal generation.
