Abstract :
This paper proposes a semi-blind LMS adaptive beamforming algorithm for antenna arrays applied to an OFDM system. The OFDM system under consideration employs the fast Fourier transform (FFT) to efficiently generate the sub-carriers. The performance of the proposed algorithm is verified by computer simulation.
