Abstract :
A system-on-a-chip baseband processor for full duplex digital communication applications is proposed. The SoC employs three 16-bit digital signal processors (DSPs), one in transmitter path and two in the receiver path. Hardware coprocessors are integrated for on chip digital down conversion, de-spreading and Viterbi decoding to give hardware acceleration in data processing. The DSP processors can be configured through software for different standards and protocols. Standard asynchronous UART interface is provided on chip for program development and debugging. Computer simulation results indicate an improvement in performance obtained when a moderately performing DSP is used as the processing engine
