摘要： 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.

摘要： Provided are a multi-pilot generation method and a detection method in a multi-antenna communication system. In the method, a transmission side superimposes a first preamble sequence and a third preamble sequence to generate a second preamble sequence, which is subjected to serial/parallel conversion before the first preamble sequence and the second preamble sequence are successively transmitted from a plurality of antennas by time division. A reception side receives the first preamble sequence and the second preamble sequence by a plurality of antennas, separates the third preamble sequence from the second preamble sequence by a spatial division process, and performs a pilot correlation process by using the first preamble sequence and the separated third preamble sequence.

摘要： A retransmitting method, a radio receiving apparatus and a multiantenna communication system that are capable of improving the system throughput. According to this method, the receiving apparatus determines whether a received substream has an error and hence a retransmittal is necessary (401); calculates a signal-to-interference noise ratio after detection of multiinput/multioutput of the substream that must be retransmitted (402); compares the signal-to-interference noise ratio of the substream, which must be retransmitted, with a predetermined threshold value (403); performs a full retransmission of the substream, which must be retransmitted, when the signal-to-interference noise ratio of the substream, which must be retransmitted, is smaller than the predetermined threshold value (404); and performs a redundant-increased retransmission of the substream, which must be retransmitted, when the signal-to-interference noise ratio of the substream, which must be retransmitted, is greater than the predetermined threshold value (405,406,407).
