在pudn找到的leach协议的源代码大多是基于这篇文章的，把原版论文和大家共享。(SEP:A Stable Election Protocol for clustered heterogeneous wireless sensor networks )

communication system is expected to increase the service, the quality improvement and also the capacity, using spread spectrum communication system is one of the method to fulfill that demand. This quality and capacity factor will depend on the number of user. In order to see the performance of the Wiener Filter on the MC-CDMA system, simulation method is used by increasing the Direct Sequence Spread Spectrum CDMA signal, with digital modulation QPSK
