Exact analysis of received signal in CDMA uplink

摘要

This paper presents exact expression for output SINR of RAKE receiver on CDMA uplink. In the derivation process, we consider the effects of spreading sequences, propagation, multiuser interference, and weight of RAKE combiner. The exact expression is obtained without any approximation. We verified the analytical results comparing with simulation results and confirmed that the analytical results perfectly match with simulation results in various conditions. The expression is applicable to system-level simulations and experiments, which provides accurate results without any computational burden.
