The spread spectrum sequence with high bit rate is used the receiver, the same spread spectrum sequence is used to modulation using the spread spectrum code sequence makes the sequence of spread spectrum code in one frame. Pseudorandom code sequences can be generated by the shift algorithm based on M spread spectrum, and the binary signal spread spectrum communication technology [N]. spread spectrum communication technology [N]. spread spectrum communication technology [N].	./cache/work_7ohmgws75fcdhfv77ad7lvpszu.pdf	./txt/work_7ohmgws75fcdhfv77ad7lvpszu.txt
