Abstract
A beamforming algorithm with a fast convergence rate, which can be applicable to an OFDM communication system,. has been proposed and the performance of the proposed scheme has been evaluated by a computer simulation. We can gain an essential convergence in the seventh step in a 16-element array configuration, in an environment with -10 dB of SNR and 10 dB interference signal power.
