摘要：There has been a dramatic change in the field of field of telelcommunication service. M-ary Quadrature Amplitude modulation and Quadrature Phase shift Keying (QPSK) modulation schemes are considered in Wideband code Division Multiple Access(WCDMA) system. Here we are using MATLAB for simulation and evaluation of BER ( Bit Error Rate )and SNR(Siganl to Noise Ratio). There is analysis of Quadrature Phase shift Keying and 16 –ary Quadrature Amplitude modulation which are being used in WCDMA (wideband code division multiple access) system. This system is more suitable modulation technique to suit the channel quality
