Abstract
In this paper,a simplified and sub-optimal wideband CDMA downlink rake receiver with Wiener combining is investigated. Pilot symbols in each of slots will be used for channel delay estimation and weight calculation. Compared to conventional combining which uses MRC(maximum ratio combining), Wiener combining which uses IRC (Interference rejection combining) can get better MAI (Multiple Access Interference) rejection. For AWGN channel and Clarke's Rayleigh Fading channel with four independent paths, we simulate the BER performance of the rake receiver with Wiener filter. From the simulation result, although we get about 1.5dB performance degraded in A WGN and 6 to 7 dB degraded in Rayleigh Fading channel as compared to the ideal performance, its simplified algorithm can be an advantage of implementation.
