Abstract :
This paper presents a DSK6711 based solution for a CDMA system. Paper contains design of analog part and coding style for DSK6711. Coding related to CDMA is done on DSK6711 that is found fast enough for this application about 1200 MFLOPS. Higher frequencies are not easy to work with therefore our design does the same work at 30 MHz using FSK modulation. QPSK however is the standard imposed by IS-95 but it is difficult to achieve using the available integrated circuits and oscilloscopes. McBSP of DSK6711 allows variable data rates to create flexibility in implementation.
