Abstract :
The paper introduces the basic modulation and demodulation principle of BPSK and BDPSK. Based on the Matlab, we study on the two kinds of modulation demodulations under the different noises. We mainly research the SNR and BER of BPSK coherent demodulation, BDPSK coherent demodulation and BDPSK incoherent demodulation. The simulation indicates the BER of BDPSK coherent demodulation is higher than BPSK coherent demodulation. If we adopt the same demodulation, the BER of coherent demodulation is lower than the incoherent demodulation under the same SNR.
