In this paper, we propose an efficient low complexity MIMO detection method for double space-frequency transmit diversity (D-SFTD) based coded OFDM system. The proposed MIMO detector involves three-step filtering process to efficiently de-correlate spatially-multiplexed and space-frequency-coded signals without direct matrix inversion process. As the proposed MIMO detector takes advantage of frequency...
Multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) is regarded as a promising technology enabling higher data rate wireless communications in frequency selective fading channels. This paper proposes the next generation wireless local area network (WLAN) physical (PHY) layer transmission technology using dual-band and MIMO-OFDM schemes and media access control (MAC)...
For higher data rate wireless communication, multiple antenna and orthogonal frequency division multiplexing (OFDM) schemes are considered as a key technology. In IEEE 802.11 TGn (Task Group n), multiple input multiple output-OFDM (MIMO-OFDM) methods, including spatial division multiplexing (SDM), are adopted for a higher throughput solution in the next generation wireless local area network (WLAN)...
