Uniform channel decomposition for MIMO communications

Assuming the availability of the channel state information at transmitter (CSIT), we propose a transceiver design which contains a linear precoder and a MMSE-VBLAST detector. We show that this transceiver design can decompose, in a capacity lossless manner, a MIMO channel into multiple subchannels with identical capacities. This uniform channel decomposition (UCD) scheme can provide much convenience for the modulation/demodulation and coding/decoding procedures due to obviating the need of bit allocation. The simulations show that the UCD scheme has excellent performance even without using any error correcting coding.
