Abstract :
Describes the digital algorithm implementation of a single DSP based 1.2 Kbits/sec Q2PSK transmitter and receiver units. Further results have been obtained with this data bit rate. The algorithm has been implemented in a system based upon the TMS320C25 for the transmitter and upon the TMS320C30 for the receiver. Both, systems and algorithms are suitable for operation up to 9.6 Kbit/sec and more research is being carried out with this data bit rate. The designs of the digital filters, transmitter and receiver are expounded
