Adaptive multiuser DFE with Kalman channel estimation for DS-CDMA systems in multipath fading channels

摘要

An adaptive multiuser decision-feedback equalizer (DFE) companioned with a Kalman channel estimation algorithm is presented for DS-CDMA systems in multipath fading channels. The Kalman channel estimation algorithm is employed to estimate the multipath fading channels, then the estimates are used to adjust the tap coefficients of the multiuser DFE via a minimum mean-square error design criterion.
