Simulation of Coherent PSK Circuit for Wireless Data Communication with Zero Bit Error Rate

A Coherent phase-shift-keyed (CPSK) wireless data communication circuit, based on differential signaling, is simulated for error-free data recovery. The simulated circuit is tested and the results are reported, indicating error-free data recovery. In these simulation tests, data with bit rates varying from 1Kb/s to 1Mb/s are transmitted through simulated AWGN channels with channel noise variance ranging from 1 to 10,000. All the test results indicate error-free data recovery.
