A Predictive Power Control Scheme for OFDM Wireless Network

摘要：

A new predictive power control scheme was considered for a wireless cellular system employing orthogonal frequency division multiplexing (OFDM). To mitigate the effect of cochannel interference CCI while satisfying required quality of service, the power level on each subchannel of OFDM systems should be allocated to and controlled at an optimum level. A conventional approach to OFDM power allocation system design is to maintain the same link quality for all subchannels. This simple scheme requires high power consumption and deteriorates control stability and convergence properties. To overcome the drawbacks of the traditional approach, a new power control scheme is proposed. Numerical results are presented to illustrate the advantages of the proposed algorithm over the conventional one.
