Abstract :
This paper focuses on the problem of detecting multiuser coded space-time signals transmitted over multi-antenna multipath channel, with imprecise channel knowledge in reception. Computationally efficient methods combining soft multiuser interference (MUI) cancellation and minimum mean square error (MMSE) processing are developed for both channel estimation and space-time soft equalization.
