Abstract

In this paper, we propose a spatial-temporal adaptive MIMO beamforming scheme for single carrier transmission in frequency-selective fading channels with an assumption of perfect channel state information (CSI) at both transmitter and receiver sides. The transmit and receive weight vectors are estimated by using an iterative update algorithm to detect the preceding signal and its delayed versions. The preceding signal and its delayed versions after detection are combined with the minimum mean square error (MMSE) criterion to maximize the output SINR at the receiver side. This improvement of output SINR is useful for MIMO systems to complement the high-quality for increasing high data rate transmission in broadband wireless communication.
