Adaptive iterative bit allocation algorithm for MIMO-OFDM system
The adaptive iterative modulation was proposed for multiple-input-multiple-output-orthogonal frequency divi-sion multiplexed（MIMO-OFDM） system.An adaptive minimum transmit power modulation scheme under constant data rate and fixed bit error rate（BER） for the MIMO-OFDM system was proposed to adjust t...

| Summary: | The adaptive iterative modulation was proposed for multiple-input-multiple-output-orthogonal frequency divi-sion multiplexed（MIMO-OFDM） system.An adaptive minimum transmit power modulation scheme under constant data rate and fixed bit error rate（BER） for the MIMO-OFDM system was proposed to adjust the modulation order and allo-cates the transmit power to each spatial sub-channel by iterative method considering the requirement of the practical communication system.It can meet the user’s requirements and get better freguency efficiency at the cost of minimum transmission power.And it can avoid the error by round the modulation order.Computer simulation results present the ef-ficiency of the proposed scheme. |
