Abstract

In this paper, we propose an efficient symbol detection algorithm and its hardware architecture for MIMO-OFDM system with two-transmit and two-receive (2×2) antennas. The detector supports two MIMO-OFDM schemes, SFBC-OFDM and SDM-OFDM, in order to achieve higher performance and throughput. However, symbol detection processes for these two schemes have high computational complexity, which is a burden to hardware implementation of MIMO-OFDM symbol detectors. In order to reduce the complexity, we propose a cost-efficient algorithm for SDM-OFDM and novel hardware architecture for MIMO-OFDM symbol detectors. The proposed detector with shared-architecture, where similar functional blocks are merged and share the hardware resources, can be used for not only SDM-OFDM but also SFBC-OFDM systems.
