Abstract
Conventional partial transmit sequence (PTS) orthogonal frequency division multiplexing (OFDM) system requires high hardware or high algorithm computational complexity to reduce peak to average power ratio (PAPR) so that signal distortion and power can be reduced during transmission. The Lim's PTS OFDM system is applied to this paper in the beginning with the aim at reducing hardware complexity. Since the emphasis of this paper is placed on subblock partitioning method, we then employ linear subblock partitioning method and realize the multiplications and the additions of radix-2 inverse fast Fourier transform (IFFT) butterfly diagram with linear characterization. We find that the complementary cumulative distribution function (CCDF) curve of linear subblock partitioning is close to that of non-linear subblock partitioning, and therefore our method can yield the same performance with more hardware complexity reduction.
