用matlab实现AWGN信道下的仿真，是WCDMA和GSM系统仿真的基础-Using matlab to achieve AWGN channel simulation, the WCDMA and GSM-based system simulation

Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne, CDMA2000 (the 3G evolution of cdmaOne) and WCDMA (the 3G stand
