In this paper, an iteration interference cancellation detector for multi-user MIMO uplink transmission system is proposed, which utilizes the special property of Orthogonal Space Time Block Code(OSTBC) equivalent channel of each user to simplify the decoding at the base station. With the proposed algorithm the number of receive antennas is significantly reduced as much as the number of users, and...
In this paper, we propose a cost efficient approach for narrowband interference suppression in direct sequence spread spectrum systems. Our proposed approach takes advantage of the multirate property by using cosine- and sine- modulated perfect reconstruction filter bank blocks of small size to form an adaptive two-stage tree-structured filter bank. In the first stage, an efficient complex modulated...
