1Introduction The orthogonal frequency division multiplexing(OFDM)system is becoming a chosen modulationtechnique for wireless communications,which canprovide large data rates with sufficient robustness toradio channel i mpairments.Recently,there have beenmany attempts to further i mprove the OFDM systemperformance.Among them,an adaptive OFDMscheme has attracted much attention[1,2],in whichmodulation mode of each subcarrier is adaptivelychanged with the channel quality.However,such i m-pr…  相似文献
