Adaptive modulation for MIMO-OFDM systems
We consider adaptive modulation in OFDM systems employing multiple transmitter and receiver antennas. The goal is to determine the optimum choice of modulation constellations from among a given set in order to minimize the transmit power, subject to a total bit rate and error rate constraint. A dyna...

Summary: | We consider adaptive modulation in OFDM systems employing multiple transmitter and receiver antennas. The goal is to determine the optimum choice of modulation constellations from among a given set in order to minimize the transmit power, subject to a total bit rate and error rate constraint. A dynamic programming based algorithm, that results in optimum selection of constellation sizes, is proposed to solve the resulting discrete optimization problem. |
