摘要：
In recent years there has been an explosive increase in the demand of radio channels in cellular communication systems. Due to the finite limit of the frequency spectrum a number of available channels is bounded. This constraint has become a bottleneck of next-generation wireless communication systems. Some array beamforming techniques have been proposed to solve this problem by the space-division multiple access (SDMA). In the paper, a fast adaptive beam-forming algorithm for extracting cyclic signals is proposed. Similar to the SCORE algorithm, the new beamformer performs a blind signal extraction. Compared with the SCORE method it has simpler computation and faster convergence rate and higher SINR in many situations of interest.
