Document Type and Number:
WIPO Patent Application WO/2018/129710
Kind Code:
A1
Abstract:
Disclosed in the present application are a signal transmission method, system and device. The method of the present application comprises: a transmitter obtaining a signal segment to be transmitted having a set length; the transmitter calculating a scaling factor corresponding to the signal segment according to a power of a signal in the obtained signal segment, and using the scaling factor corresponding to the signal segment to scale the amplitude value of the signal in the signal segment; the transmitter transmitting the scaling factor corresponding to the signal segment and the scaled signal segment to a receiver. The present application may reduce the PAPR of a signal, and solve the problem wherein high PAPR in a signal may lead to distortion of an output signal of an RF power amplifier.
