摘要
提出了一种基于DFT线性和循环移位性质的子载波预留方案,即利用DFT变换的线性和循环移位性质,使用非预留子载波产生削峰信号,利用预留子载波传输峰值信号的幅度、相位和位置等信息.仿真结果验证了此改进算法的有效性.
In this paper, a new tone reservation method based on the linearity and cyclic shift properties of the DFT is proposed. In this scheme, the cancellation signals are generated by the information tones, the reserved tones are used to transmit the altitude, phase and position of the peak signals. Computer simulation verified the efficiency of the new method.
