Abstract
A wireless communication system capable of achieving adaptive STTD (Space-time Transmit Diversity). In this system, a receiving apparatus uses a channel estimation to calculate SINR (Signal to Interference and Noise Ratio) of each of substreams in all the combinations of transmission antennas and also calculate the performance of the whole system in all the combinations of transmission antennas, thereby deciding a particular combination, which provides the best performance of the whole system, and obtaining a parameter for antenna selection. The SINR of each substream in the decided particular combination is used to decide an AMC parameter. A transmitting apparatus performs STTD and AMC based on the AMC parameter fed back from the receiving apparatus, and further selects, based on the antenna selection parameter fed back from the receiving apparatus, a particular combination of transmission antennas for performing a transmission.
