Research on the Performance of 2-D RAKE Receiver for CDMA System
Yao Li · Modern Electronics Technique · 2009
In Code-Division Multiple Access(CDMA) system,Multiple Access Interference(MAI) and Inter-Symbol Interference(ISI) are caused due to multiple users transmitting at the same time and frequency,and the existence of multi-path fading while signal transimitting through the wireless channel.As a result,the performance of system receiver degrades.Space-time receivers(2-D RAKE) can effectively suppress MAI and fight against MPI.In this paper,the characteristics for several space-time receivers are discussed.At the same time,each receiver is analyzed and compared detailedly.
