Abstract

In this paper, MIMO techniques for suppression of ISI and MAI in frequency-selective fading channels are evaluated analytically and by means of link level computer simulation in a UTRA-TDD like system. Equalization of the spatio-temporal channel matrix is either performed at the transmitter via joint predistortion (JP), at the receiver via zero-forcing block linear equalization (ZF-BLE) combined with symbol cancellation (ZF-B-BLAST), or balanced at both sites of the channel via space-time vector coding (STVC). The computational complexity of all presented approaches is reduced by the introduction of blocked block-circulant system matrices
