| Abstract: | An optimized channel estimation scheme, which could be easily implemented in 1C, is proposed in this paper. Elaborate theoretical analysis concerning the principle downlink of WCDMA physical layer is given. Results of computer simulation for frequency-selective fading channel show that using our optimized channel estimation scheme, at least 2dB improvement can be achieved. |
