| Abstract: | Using the spatial dimension provided by the adaptive antenna arrays,the spatial temporal domain singal receiving can substanically reduce the effect of multiple access interference (MAI) and multipath fading and thus improve the system performance.In this paper,we have studied the structure of RAKE receivers with antenna arrays and deduced the performance of the extended 2 D RAKE receiver which is combined by MMSE beamforming and 1 D RAKE receiver.Furthermore,a method of estimating the channel parameters of system expected signal has been given. |
