Analysis of Maximal Ratio Combining Performance in CDMA20001x Mobile Radio Network
Recently, wireless communication systems support not only voice communication but also other high-speed data and multimedia services. These services require high data rates with low delay and Bit Error Rate (BER). But, it is difficult to support these requirements with wireless systems due to some constraints in the system design. First of all, wireless systems operate over a complex and harsh time-varying radio channel which originates due to severe multipath and shadow fading. In addition, wireless applications must share the limited available radio spectrum, and spectral efficiency is therefore of primary concern in the system design.
