The orthogonal frequency division multiplexing (OFDM) modulation technique is one of the key strategies for multiuser signal\r\ntransmission especially in smart grids and wind farms. This paper introduces an approach for peak-to-average power ratio (PAPR)\r\nreduction of such signals based on novel global harmony search (NGHS) and partial transmit sequence (PTS) schemes. In PTS\r\ntechnique, the data block to be transmitted is partitioned into disjoint subblocks, which are combined using phase factors to\r\nminimize PAPR. The PTS requires an exhaustive search over all combinations of allowed phase factors. Therefore, with respect to\r\nthe fast implementation and simplicity of NGHS technique, we could achieve significant reduction of PAPR.
