摘要
Abstract
An improved partial transmit sequences (PTS) method to reduce the high PAPR of OFDM systems is proposed in this paper. First, the original signal is separated into several subblocks. Second, each subblock is multiplied by a precoding matrix composed of the Discrete Hartley Transform matrix. At last, the Inverse Fast Fourier Transform is applied to every subblock in PTS system. Theoretical analysis and simulation results show that the improverd PTS method has more effect on further reducing PAPR of OFDM systems than the tranditional PTS method.关键词
