| Abstract(in English) | The Multiple Input Multiple Output (MIMO) technique is motivating the world-wide researchers to realize the next generation wireless LANs with the higher channel capacity and higher signal quality. This paper proposes and analyzes the Spatial Division Multiplexing (SDM)-OFDM svstem with adaptive modulation method over MIMO channels for wireless LANs. We propose the Carrier-to-Noise Power Ratio (CNR) estimation method for each OFDM sub-carrier over multi-path fading channels, which can be used for the assignment of the optimal modulation scheme to each sub-carrier in each transmit antenna. In regard to realistic considerations, we also propose the adaptive modulation aided SDM-SCOFDM (Single Carrier OFDM) system that can reduce the number of required feedback adaptive modulation information (AMI) bits remarkably and also improve the PAPR (Peak to Average Power Ratio) performance. This paper presents the various computer simulation results to verify the proposed methods under a typical wireless LAN environment. |
