Reduced Complexity Blind Layered Space-Time Equalization for MIMO OFDM Systems
Overview This paper proposes reduced complexity blind Layered Space-Time Equalization (LSTE) for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM). Blind Source Separation (BSS) combined with a Vertical Bell Laboratories Layered Space-Time (V-BLAST) scheme is used in a small portion of subcarriers to perform blind signal detection and channel estimation iteratively. In the remaining subcarriers the Channel State Information (CSI) is obtained by interpolation using the previously acquired CSI, and signal detection is subsequently carried out with a V-BLAST scheme.
