This contribution deals with the performance of joint spacetime multi-user turbo carrier phase and propagation delay estimation in a bit interleaved coded modulation scheme for asynchronous Direct-Sequence Code Division Multiple Access (DS-CDMA) transmission over frequency selective, slowly fading channels. As it has great impact on the overall BER performance, accurate estimation of the channel parameters is critical. We present an iterative Space-Time Multi-User (STMU) turbo detection anddoi:10.1109/isccsp.2004.1296559 fatcat:lnckjwxfszbzbhiorecaw75e7q
