Abstract: Spread spectrum communication is the most efficient mode in the strong noise environment such as the coal mine. This article introduces the the principle of the DS communication technic.It indicates that the DS communication anti-jamming technic is especially applicable to the strong noise environment.The spread spectrum communication can reduce high request to the Signal-to-Noise, especially can overcome some defects caused by multiple-path effect and noise, including feeble anti-interference ability and poor speech quality.At last the article introduces the generator and pertinency of the m-sequences ,and uses the MAX+PLUS II of the ALTERA to simulate.

摘要: 扩频通信是矿井等强噪声环境中最有效的通信方式。文章介绍了扩频通信中直扩通信方式的技术原理,指出直扩抗干扰技术特别适用于强噪声环境,能降低通信系统对信噪比的高要求,克服机电噪声引起的抗干扰能力弱、通信质量差以及可靠性低等弱点。最后介绍了作为扩频码的m序列的发生器及其相关特性,并给出了仿真结果。
