Abstract:
1. A wireless communication system including a transmitting device having a plurality of antennas, transmitting different radio signals from each of the plurality of antennas and communicating with a plurality of receiving devices, and the plurality of receiving devices each having at least one of antennas and receiving the radio signals transmitted from the transmitting device, each of the plurality of receiving device comprising: the transmitting device comprising: wherein the transforming unit holds the used change-of-variable matrix that was used in a previous transforming, detects the latest transmission path information from the detected transmission characteristic information and the used change-of-variable matrix, obtains the latest change-of-variable matrix from the latest transmission path information and the detected transmission characteristic information and transform the respective transmission data by multiplying the respective transmission data by the latest change-of-variable matrix.
