In this paper, a combined switched beam-forming and adaptive beam-forming algorithm is proposed for orthogonal frequency division multiplexing (OFDM) systems with antenna arrays in multi-path fading channels. Firstly, multiple beams are generated by using a set of known weight vectors to cover the direction of arrival (DOA) range from 0 to 360 degrees.(More)
