A direction phase shift keyed communication system provides the capacity to transmit any one of two symbols for each modulation level. The modulator produces a substantially constant frequency signal which includes a phase transistion in respect of each information bit. In a system with a single ...

Abstract:According to the principle and mathematical model of 2PSK modulation and demodulation,the 2PSK system is simulated based on LabVIEW. By adjusting the parameters of carrier frequency and code rate,the simulation results of 2PSK system with different parameters are observed. Simulation results ...
