Description: Transmitter design is the use of m sequence to expand the binary data stream, the spread spectrum is a broadband signal, and the use of QPSK modulation mode to send out the signal modulation. The signal is transmitted to the receiving end via the AWGN channel. The receiver uses the coherent demodulation principle and demodulation signal, and the sequence of the code sequence is identical with that of the transmitter.
