PROBLEM TO BE SOLVED: To provide a receiver included in a multi-user MIMO system which obtains a channel gain while reducing the amount of feedback information. SOLUTION: The receiver having N (N≥4) pieces of antennas has a plurality of synthetic quantizers for synthesizing M channel vectors corresponding to M (2≤M≤N-2) pieces of the antennas, and selecting a predetermined quantization vector corresponding to the synthetic vector of the M channel vectors, wherein the index of the predetermined quantization vector selected at each synthetic quantizer is fed back to a transmitter.
