Since the publication of Alamouti’s famous space-time block code, various quasi-orthogonal space-time block codes (QSTBC) for multi-input multi-output (MIMO) fading channels for more than two transmit antennas have been proposed. It has been shown

In this paper, we discuss the potential of wireless systems employing multiple antenna elements at both sides of the link. Diversity gain and multiplexing gain are explained and related coding techniques allowing to realize these gains are presented.

Trellis-coded modulation (TCM) concatenated with phase precoding is proposed to alleviate the effect of intersymbol interference (ISI) in frequency selective slow fading channels in wireless communications. Simulation results show that gains of 6.5 a

The performance of a wireless system can be significantly improved by using multiple antenna elements at the transmitter and/or the receiver side. The major problems of such systems are high cost and complexity due to more than one radio frequency (R

The error performance of a new family of super quasi-orthogonal space-time trellis codes (S-QSTTCs) for four transmit antennas on correlated MIMO channels is investigated. Two slightly different designs of S-QSTTCs, namely S-QSTTCs obtained by concat

We analyze and compare transmission schemes that apply nonorthogonal space-time block codes in uncorrelated and correlated MIMO channels using four transmit antennas and a zero-forcing receiver. The ABBA code and a slightly different code, the so-cal
