Abstract :
Adaptive modulation and power management has recently been considered as an efficient means to boost communication performance in MIMO-OFDM system. In this work, a new scheme of joint modulation and power management is investigated. It adopts the implementation of a Signal-to-interference-Noise-Ratio threshold and MQAM-MPSK hybrid modulation structure for every parallel subchannel. The simulation result displays that this approach efficiently achieves a lower BER in contrast to other adaptive modulation schemes with the same Eb/NO, as both 16QAM and QPSK.
