| Abstract: | The use of multiple antennas at the BS (Base Station) allowssignificant improvements on the spectral efficiency of wirelesscommunications systems by increasing the number of simultaneoususers on a given cell. In this paper we introduce a new iterative multiuser detection scheme for systems requiring high-rate transmission in severe time-dispersive channels. We consider the use of single-carrier modulations combined with frequency-domain equalization techniques, which are known to be excellent candidates for severe time-dispersive channels. The BS employs multiple antennas and consists of an iterative LST (Layered Space-Time) receiver combined with frequency-domain equalization techniques. Our performance results show that the proposed receiver structure has excellent performance, which can be very close to the matched filter bound, even for severe time-dispersive channels and in the presence of strong interfering channels. | ||
