Bit-Interleaved Coded Multiple Beamforming With Perfect Coding

When Channel State Information (CSI) is available at both the transmitter and the receiver, beamforming techniques exploiting Singular Value Decomposition (SVD) are applied in a Multiple-Input Multiple-Output (MIMO) system to achieve spatial multiplexing1 and thereby increase the data rate, or to enhance the performance. However, spatial multiplexing without channel coding results in the loss of the full diversity order. To overcome the diversity degradation, Bit-Interleaved Coded Multiple Beamforming (BICMB), which interleaves the codewords through the multiple subchannels with different diversity orders, was proposed.
