Bit and Power Loading Game of the Flexible OFDM Transceiver in a Wireless Environment

In this paper, flexible operation of an OFDM transceiver in a wireless environment is considered in the framework of the game theory. The intelligent control unit of the transceiver, playing the bit-and-power loading game against the radio channel is assumed to have limited, erroneous or obsolete channel state information. The strategies, utilities and payoffs of the game are defined. Simulation experiments show that the well-suited choice of the utility function, reflecting user's preferences for throughput maximization and the power economy has a near-optimum effect on bit rate and power consumption under the assumed bit-error probability and mean power constraints.
