A NOVEL PAPR REDUCTION WITH TRELLIS SHAPING FOR NC-OFDM IN COGNITIVE RADIO被引量：1
《Journal of Electronics(China)》2009年第3期296-302,共7页Shao Fei Yu Yong Zhang Shijie Sun Dechun 
Supported by the National Natural Science Foundation of China (No.60832008);National Basic Research Program of China (973 Program, No.2009CB320403)
In this paper, trellis shaping is applied to reducing the Peak-to-Average Power Ratio(PAPR) of NC-OFDM signals due to the fact that the total number of active subcarriers and their locations might change continuously ...
