| 20110142154 | SEQUENTIAL TRANSMISSION MULTI-BEAMFORMING METHOD WITH LOW COMPLEXITY USING HADAMARD MATRIX - Provided is a sequential transmission multi-beamforming apparatus and method with a low complexity based on a Hadamard matrix. A simple codebook may be generated based on the Hadamard matrix and thus, a number of weighted-vectors is reduced and a complexity of hardware is decreased. A diversity gain may be maximized based on a spatial diversity processing apparatus and a beamforming weighted vector may be systematically generated. | 06-16-2011 |
