| Summary: | 碩士 === 國立中央大學 === 通訊工程研究所碩士在職專班 === 96 === We quote Zhang’s subcarrier distributes method to establish initial subcarrier distribution. And double check if we exchange or shift more pair subcarriers at the same time, the transmit power decreasing degree can be more and fast. Simulation results show that if we use better subcarrier allocation at the beginning, and change more subcarriers at the same time if the power gain will be more. The needed final total transmit power will be less.
