MATLAB下用Matched-z 变换设计低通，高通，带通，带阻数字滤波器设计(Using MATLAB m-file to design LP, HP, BP and BS fitlers by matched-z transformation.)

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
