Abstract

In the implementation of SVD-MIMO transmission, with a small number of antennas simplifies the build process and ensure satisfactory decoding capabilities. The transmitter based on the reference signal transmitted from the receiver, the estimated channel information to determine a transmit antenna weighting coefficient matrix, calculating the weights assigned to each of the multiplexed signal component weight of the respective signal components of training signals based on the channel information transmitted to the receiver, the training signal is to calculate the weight of the weighting. On the other hand, the receiver determines a receive antenna weighting coefficient matrix based on the received training signal.
