- W2057487415 abstract "Orthogonal frequency division multiplexing (OFDM) is one of the preferred choices for high speed transmission of data in wireless domain pertaining to its immunity towards inter-symbol interference. However high value of peak to average power ratio (PAPR) is a major problem associated with OFDM. High PAPR increases circuit complexity and reduce RF amplifier efficiency. Partial Transmit Sequence (PTS) is one of the widely used techniques for PAPR reduction, however in PTS scheme the computation of optimal phase factors necessitates exhaustive searching among all allowable phase factors. This leads to exponential increase in search and computational complexity with the increase in number of subblocks. In this paper a PTS scheme using Genetic algorithm (GA) for optimized search with low computational complexity scheme is proposed. The proposed scheme provides efficient search and PAPR performance at low computational complexity for a given value of PAPR threshold." @default.
