| Abstract: | In this paper, an improved decision feedback receiver is presented for the CDMA IS-95 reverse link. Two techniques are proposed to improve the receiver performance: (1) noncoherent block detection that uses multiple Walsh codes for joint detection, and (2) iterative decision feedback detection. Comparing with conventional "decision feedback receiver," a significant performance improvement is observed via the computer simulations for both AWGN and Rayleigh flat fading channels. |
