The Research of Improved PTS Method for Peak-to-Average Power Ratio Reduction

摘要：

One of the main drawbacks of orthogonal frequency division multiplexing (OFDM) is the high peak-to-average power ratio (PAPR) of the OFDM signal. How to reduce the PAPR is the key to applying the technology of OFDM efficiently. In this paper, two new methods to reduce the PAPR of OFDM signals based on the combination of Clipping or matrix transform with PTS are presented. Then PAPR is reduced by using the combination method through simulation. Simulation results have shown that the proposed methods are very effective and flexible to improve PAPR performance in the MIMO-OFDM.
