Patent ID: 8107896

Claim:
A mobile communication system comprising: a transmitting station; and a receiving station, wherein said transmitting station comprises: an encoder which encodes a transmit signal; and a modulator which modulate the transmit signal output from the encoder, separates the modulated transmit signal into M units of modulated signals (2≦M), and an operation unit which multiplies M units of modulated signals separated and output from said modulator by a complex matrix consisting of M×L units of elements, and performs beam forming of the M units of modulated signals; a plurality of antennas which transmit L units of beam formed transmit signals (2≦L), and wherein said receiving station comprises: a plurality of antennas which respectively receive the signals transmitted from said plurality of antennas of said transmitting station; a Multiple-Input Multiple-Output (MIMO) receiver which separates said plurality of signals from the signals input from said plurality of antennas; a demodulator which demodulates the plurality of signals output from said MIMO receiver; and a decoder which decodes said plurality of demodulated signals.
