BPSK (Binary Phase Shift Keying)-------二进制相移键控。是把模拟信号转换成数据值的转换方式之一，利用偏离相位的复数波浪组合来表现信息键控移相方式。BPSK使用了基准的正弦波和相位反转的波浪，使一方为0，另一方为1，从而可以同时传送接受2值(1比特)的信息。(- binary phase shift keying. It is one of the ways to transform analog signals into data values, and to use the complex wave combination that deviates from the phase to show the information key shift phase mode. BPSK uses a sine wave and a phase reversal wave to make one party 0 and the other side 1, so that 2 values (1 bits) can be transmitted at the same time.)
