  1. There are many ways of modulating signal about bpsk such as castas loop, square loop, etc. usually the carrier wave is put forward firstly, then the purified carrier wave is used to demodulate the output data ( all these things are usually completed in the same loop ). these methods have their strong points but at same times, it is difficult to design and achieve these ways
