摘　　要：研究了一种将M元扩频和纠错码相结合的通信方案。由于采用了M元扩频,在带限信道中获得了较高的数据传输速率;同时采用纠错编码,增强了系统的可靠性。两者的结合,较好地解决了通信系统有效性与可靠性两大问题。仿真结果表明该系统具有很好的性能。A communication method combined M_ary spread spectrum with error correcting code is studied. The application of M_ary spread spectrum makes it easy to acquire high transmission rate. On the other hand, the application of error correcting code enhances the reliability of the communication system. The problem of availability and reliability is solved by combining the two kinds of technology. Simulation results indicate the system has good performance.
