摘要

To cope with the deleterious channel fading effects on the system performance, diversity-enriched transmitters and receivers have well-appreciated merits. When the channel state information is available at the transmitter, precoders are designed to suppress the channel effect and enable the diversity and low-complexity receiver designs. In addition, the peak-to-average power ratio (PAR) issue has to be considered from the energy perspective. In this paper, after reviewing existing precoding designs by providing the diversity and PAR results, we present a low-complexity transceiver design with a geometric mean decomposition based precoder at the transmitter and a novel lattice reduction aided equalizer at the receiver. The performance is analyzed in terms of diversity and the PAR. The theoretical analysis is corroborated by computer simulations.
