Abstract

Abstract: A receiver model is developed on a direct-spread code-division multiple-access system, and a blind beamforming algorithm is proposed based on the model. Therelationship of the subspace of the received signal and the spreading code of the desired user is used to get coefficient of beamformer. Simulations have demonstrated that the algorithm performs better than other blind beamforming algorithms.

Key words: DS-CDMA, beamforming, subspace, spreading code
