Patent ID: 7561850

Claim:
A wireless receiving apparatus capable of communicating with a wireless transmitting apparatus that implements a closed-loop transmit diversity scheme using a first antenna and a second antenna, comprising: an antenna verification unit verifying 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, wherein 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 weight vector 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, the antenna verification unit execute verification 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.
