| Abstract: | OFDM techonology find application in the High-Definition TV system.But the high Peak-to-Average Power Ratio(PAPR) is a main drawback in OFDM system.This paper make researches on the usual algorithms of reducing PAPR and propose a combined algorithm which is based on the PTS algorithm and Companding algorithm.Simulations results indicate that the PAPR of OFDM system can be efficiently reduced with low computational complexity by using the practicable combined algorithm. |
