Space-Time Code Selection Using Channel Prediction

Abstract

A channel prediction based space-time code selection technique for multiple input-single output systems is proposed. This transmit antenna diversity technique selects both the space-time code and the number of transmitter antennas using estimated and predicted channel state information. Linear channel prediction, designed to be optimal in the mean-square sense, has been used. Simulation results show that the proposed technique achieve SNR gains up to 2dB at high SNRs and high mobile speed.
