本文在4PSK相干解调的基础上,对引入的码变换器作了分析,以十分清晰、简明易懂的方式导出了极性比较法4DPSK解调器的误码率公式,从而得出极性比较法4DPSK解调的误码率优于相位比较法解调,近于绝对相干解调的结论。
Based on the 4PSK coherent demodulation, this paper analyzes the introduced code converter, and derives the BER formula of 4DPSK demodulator in the polarity comparison method in a very clear and concise way so as to get the polarity The BER of the 4DPSK demodulation method is better than that of the phase comparison method, which is close to the conclusion of absolute coherent demodulation.
