Abstract :
The bit error probability for BPSK modulation over correlated Rice fading channel is derived for minimum mean square error channel estimation using pilot symbol assisted modulation and diversity combining at the receiver. The optimal pilot-to-data power ratio is studied for different Rice K factors. The theoretical result is verified by Monte-Carlo simulation with space diversity fading model
