Abstract
An SVD-MIMO transmission compresses the amount of information to be fed back to a transmitter from a receiver. The transmitter and the receiver share a representation form of (amplitude, phase) for representing data to be transmitted, i.e., a form of converting real data into complex data. In other words, transmitted data is allocated to a signal point in the signal space corresponding to the data value for data transmission. The data receiver extracts an original data value according to a combination of amplitude and phase at a received signal point. The receiver can compress the information amount of transmission data.
