摘要: In future wireless communication system, beam-forming plays an important role in improving link quality. As a result, the angle information is required. In this paper, a low complexity joint angle-of-arrival (AoA) and channel estimation for single-input-multiple-output (SIMO) OFDM system is considered. By exploiting the sparsity of wireless channel, we first propose a compressive-sensing (CS) based channel estimation for pilot-assisted OFDM systems with multiple receive antennas. Then, a low-complexity method is proposed to conduct AoA estimation. Finally, simulations are provided to show the effectiveness of the proposed scheme.
