ABSTRACT
Typically the objective of a digital communication system is to transport digital data between two or more nodes.Recently, a global third generation cellular system based on W-CDMA is being developed with a wider bandwidth than existing second generation system. The Diversity Receiver instead of completely eliminating multipath uses techniques to effectively utilize multipath to produce the desired signal. This paper proposes Performance Analysis on Modulation Techniques in W-CDMA on basis of BER performance. We are going to compare between different modulation techniques such as BPSK,QPSK,M-ary-QAM.By implementing the different modulation techniques, we analyze that the variation of BER for different SNR. Proposing aim of the study are- 1) Design and Implementation of Diversity Receiver 2)To achieve higher data rate and also which one has higher BER
