Interference cancellation for improved channel estimation in array processing MLSE receivers
Array processing techniques provide significant gains in performance for digital cellular communications systems. While array processing has the potential of mitigating severe co-channel interference, performance is limited by the need to estimate the channel of the desired signal. In this paper, practical approaches for improving channel estimation in the presence of interference are proposed. Simulation of these approaches for the IS-136 TDMA cellular system demonstrate that improved channel estimation can provide gains in C/I as high as 8 dB at 1% BER.
