摘要：

Orthogonal frequency-division multiplexing (OFDM) with multiple transmit and receive antennas (MIMO-OFDM) and adaptive bit-loading (ABL) offers reliable high-data rate communication for systems with moderate mobility as considered in e.g. IEEE 802.16e. In this paper, we propose and optimize wrapped space-time coding (WSTC) for bit-loaded MIMO-OFDM. We further optimize V-BLAST with ABL by mitigating error propagation inherent in its detection process. We compare their performances with benchmark schemes known from the literature. Simulation results show that WSTC-based MIMO-OFDM achieves excellent error rate performances while feedback requirements for loading are low.
