초록
MIMO-OFDM schemes with SDM have been studied for high speed multimedia systems. However, since accurate received MIMO signal detection is very hard, MIMO-OFDM systems have not reached the available capacities. For high detection performance and low complexity, we propose efficient K-best detection technique. The proposed technique increases the detection performance by using OSIC scheme for initial detection. And to reduce the complexity, the computations for K- best algorithm are limited by OSIC scheme. The proposed technique can detect the transmit signal more accurately and offer lower complexity than conventional ZF-K- best algorithm. © 2009 IEEE.
