This paper introduces a principal concept of MIMO bit division and presents its performance with corresponding simulation results. When multiple antenna technique is applied to enhance the spectral efficiency, the original data stream should be divided in a proper way. We found that the way of dividing original data stream, if it is not cooperating well with the originally structured system, may lead to performance degradation. The key idea is dividing the original data bit stream without causing an undesired change of bit order at the output of bit-to-cell demux.
