抄録

In the compressing and expanding (companding) method, at the transmitter, baseband signals are compressed for reducing peak-to-average power (PAPR) and at the receiver, the received signals are expanded for removing the distortion caused by the compressing. However, since the signals are distorted by the band pass filter (BPF), the high power amplifier (HPF), and the channel fading, the distortion caused by the compressing cannot be removed by expanding the received signals. We propose the novel companding system that compensates the distortions caused by not only the compressing but also the BPF, the HPF, and the fading. From the computer simulation, we show that the proposed companding system achieves better BER than the conventional one with the same level of the spectrum in the out-of-bandwidth.
