Claim Text:
1. A method for transmitting a beamforming matrix of a subcarrier on a channel of a Multiple Input Multiple Output (MIMO) channel of a MIMO system by a transmitter in response to a feedback request from a receiver for obtaining channel information in the MIMO system, comprising: determining, by the transmitter, a maximum value m determining, by the transmitter, an M bits quantization of m determining, by the transmitter, a quantization amplitude M determining, by the transmitter, a linear part M determining, by the transmitter, a N determining, by the transmitter, a quantized beamforming matrix V V min(2 N −1 −1, representing a minimum value of (2 N −1 −1) and round representing a rounding operation; “| |” representing an absolute operation; and c being a positive real number; and transmitting, by the transmitter, said quantization amplitude M
