Patent attributes
A wireless receiving apparatus according to an embodiment of the invention can communicate with a wireless transmitting apparatus that implements a closed-loop transmit diversity scheme using a first antenna and a second antenna. An antenna verification unit of the wireless receiving apparatus verifies a weight vector added to at least one of a signal sent from the first antenna and a signal from the second antenna by the wireless transmitting apparatus based on feedback information from the wireless receiving apparatus. Further, the antenna verification unit compares a reception signal with a plurality of weight vector candidate values that are determined based on a previously verified weight vector to select a weight vector set by the wireless transmitting apparatus from the plurality of candidate values, and if a weight vector added to a signal received from the wireless transmitting apparatus does not match a weight vector that is determined based on the feedback information in the past verification of the weight vector, verification is carried out by adding to the plurality of candidate values, a weight vector candidate value obtained when the weight vector determined in the past verification is assumed as the weight vector that is determined based on the feedback information.
