摘要：In a peak-to-average power ratio (PAPR) reduction method for an orthogonalfrequency division multiplexing (OFDM) system based on path finding, the method
applied to the OFDM system uses an ant colony optimization (ACO) algorithm and a PTSto reduce a PAPR value, and an area of a computing circuit. In a simulated result, themethod can reduce the PAPR effectively, and can be executed by a lower level ofcomplexity of the computation. To solve a large matrix of the PTS, an ant colonyoptimization algorithm is used for calculating phase rotation vectors of a better qualityeffectively to achieve the effects of improving the performance, overcoming the highlevel of complexity of the computing circuit, and reducing the large area of thecomputing circuit.
