TRANSMITTING IN NON-BEAMFORMING MODE WITH A BEAMFORMING ANTENNA ARRAY

摘要

An apparatus (10) comprises a beamforming antenna array which includes n antennas (14₁ to 14_n) having k antenna elements (15₁₁ to 15_1k,..., 15_n1 to 15_nk), n being an integer greater than one and k being an integer greater than zero. The apparatus (10) further comprises n transmitters (13₁ to 13_n) provided in correspondence with the antennas (14₁ to 14_n), each of the n transmitters having an average transmit power of 1/n of the total transmit power, and a processor (11) which splits a signal to be radiated in a non-beamforming mode into n adjacent frequency ranges, thereby obtaining n split signals, and applies the n split signals to the n transmitters (13₁ to 13_n) such that power is distributed equally to all (n x k) antenna elements (15₁₁ to 15_1k,..., 15_n1 to 15_nk).
