Abstract

The invention relates to a signal preprocessing method and device based on phase compensation, and the method comprises the steps: carrying out the amplitude limiting of a to-be-transmitted bit signal, so as to obtain an amplitude-limited bit signal, and carrying out the phase compensation of the amplitude-limited bit signal according to the phase distortion characteristics of an amplifier, so asto obtain a phase-compensated bit signal; and amplifying the bit signal after phase compensation to obtain an output.

Description

technical field [0001] The present invention relates to a wireless communication method and device, in particular to a signal preprocessing method and device based on phase compensation. Background technique [0002] Multi-carrier signals are widely used in existing wireless communication technologies. Due to the high peak-to-average ratio of multi-carrier signals, there are strict requirements on system hardware facilities such as RF power amplifiers. In the actual system, the transmitted signal processed by the amplifier has larger nonlinear distortion than the ideal signal. This not only limits the amplification efficiency of the amplifier, but also affects the detection performance of the receiving end. Therefore, waveform signal processing at the transmitter is very important in the design of practical wireless communication systems, especially in high-power transmission systems. [0003] The existing signal preprocessing technology processes the signal amplitude and...
