A Power Allocation Scheme for M-QAM modulated MIMO-OFDM Systems Based On The Global BER Optimization

This paper proposes a novel transmit power allocation for QAM modulated Multi-Input Multi-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) transmission. This technique consists of adapting the power allocation in the spatial domain in term of the channel conditions by the optimization process based on the optimality of the global Bit Error… CONTINUE READING
