Abstract:

Precoding and space-time block coding(STBC)techniques using the uniform channel decomposition(UCD)are proposed to improve the bit error rate(BER)of the multiple-antenna communication system, but at a cost of a reduced data rate. In order to achieve a higher overall system performance, a novel adaptive transceiver architecture which flexibly combines both UCD and UCD+STBC technologies is proposed. The channel state information(CSI)feedback path was added to the precoder to select which coding method was to be used, i.e. UCD alone or UCD+STBC. With the smaller constellation sizes, Matlab simulation results show that, the adaptive transceiver architecture will select the UCD-only mode under the higher SNR conditions in order to achieve a higher bit rate. The UCD+STBC mode will be selected under the lower SNR conditions(e.g., SNR < 10 dB)in order to maintain good BER performance at the cost of a reduced data rate. This architecture was implemented and verified using both UMC 0.18 ASIC process technology and a Xilinx xc4vlx Virtex-4 FPGA at 150 MHz. The simulation results demonstrate that the required number of reconfigurable arithmetic unit slices grows linearly with the channel matrix size, while the number of adder array unit and reconfigurable logic unit slices increases slightly with the constellation size.
