| Summary: | 碩士 === 國立中興大學 === 電機工程學系所 === 104 === In this thesis, we proposed some modified search algorithms of weighting vectors based on the conventional partial transmit sequence (PTS) technique to solve peak-to-average-power-ratio (PAPR) problem in an orthogonal frequency division multiplexing (OFDM) system. On the base of RC-PTS algorithm, our main method adopt a recursive way by selecting a pre-optimized weighting vector as the starting weighting vector at next round of the algorithm. Simulation results show that with a good quality of a starting weighting vector, the RC-PTS can achieve better performance.
