-
摘要: 提出了一种基于时间测量的BPSK信号解调方法 ,介绍了解调原理并给出了实验结果。该方法属于非相干解调方式 ,可以采用软件解调 ,需要的硬件电路很少 ,而且可以产生数据的同步时钟。该方法适合中低速大信噪比BPSK信号的解调Abstract: A demodulation method of BPSK signal based on time measurement was presented in this paper. The theory of this method was introduced, and the experiment and its results were given too. It is a noncoherent demodulation method and can be achieved by software. So, little additional hardware is needed to implement the demodulation. Moreover, a clock can be generated to synchronize output data. This method is suitable for the demodulation of middle and low speed BPSK signal with large SNR.
