Diversity Analysis of Bit-Interleaved Coded Multiple Beamforming With Orthogonal Frequency Division Multiplexing

Substantial research and development interest have been drawn on Multiple-Input Multiple-Output (MIMO) systems because they provide high spectral efficiency and performance in a given bandwidth. In a MIMO system, beamforming techniques exploiting Singular Value Decomposition (SVD) are employed to achieve spatial multiplexing and thereby increase the data rate, or to enhance performance, when the Channel State Information (CSI) is available at both the transmitter and receiver. For flat fading channels, single beamforming carrying only one symbol at a time achieves full diversity. However, spatial multiplexing without channel coding results in the loss of the full diversity order. To overcome the performance degradation, Bit-Interleaved Coded Multiple Beamforming (BICMB) was proposed.
