摘要
A companding technique based on threshold is proposed to reduce the PAPR of OFDM signals. In this technique, only the signals, whose amplitudes are higher than the threshold, are compressed in the transmitter; Using a simple judgment process, the expanding operation will be executed to the compressed signals in the receiver. Compared with other scheme, the threshold companding scheme effectively improves the performance of PAPR by introducing a simple threshold judgment process.
