| Zusammenfassung: | The invention discloses a spread spectrum communication method and system. The method comprises the following steps: establishing a communication channel; using the M sequence as a spreading code, and using the spreading code to carry out spread spectrum processing on the sending information to obtain spread spectrum information; modulating the spread spectrum information by adopting a modulation algorithm to obtain modulation information; sending modulation information through the communication channel; receiving modulation information; demodulating the modulation information by adopting a demodulation algorithm to obtain spread spectrum information; and performing de-spreading processing on the spread spectrum information by adopting the spread spectrum code to obtain receiving information. According to the invention, the M sequence is used as a spreading code, the transmitted information is spread, the bit error rate of a spread spectrum communication channel is greatly reduced by using the high-strength a |
