Per-Antenna-Coded Schemes for MIMO OFDM
Overview Two Per-Antenna-Coding (PAC) receiver schemes for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) are described and compared in this paper. In MIMO, the data to transmit are multiplexed onto different antennas. With PAC (sometimes called horizontal coding), these different data streams are encoded separately. For the receiver, two schemes are proposed to detect and decode the PAC transmission. One is based on Soft-decision Output Maximum Likelihood Detection (SOMLD), the other on V-BLAST. When forward error correcting decoding is included in the Successive Interference Cancellation loops of V-BLAST, its performance is shown to be comparable with that of SOMLD.
