Problems solved by technology

If the peak-to-average ratio of the input waveform signal is high, the D / A conversion and power amplifier devices are required to have a large dynamic range, otherwise it will cause signal distortion and affect system performance
Large dynamic range D / A conversion and power amplifier devices have high power consumption, low energy efficiency, and relatively high prices, which are unaffordable for most equipment

Abstract

The invention discloses a communication processing method, a processor and communication equipment. The communication processing method comprises the following steps of carrying out offset orthogonal amplitude modulation on data so as to acquire a symbol after the offset orthogonal amplitude modulation in a time domain; carrying out Fourier transform on the symbol after the offset orthogonal amplitude modulation in the time domain so as to acquire a frequency domain signal after the Fourier transform; carrying out frequency domain forming on the frequency domain signal after the Fourier transform so as to acquire a frequency domain signal after the frequency domain forming, wherein a conjugate symmetric frequency point is removed in the frequency domain signal after the frequency domain forming; mapping the frequency domain signal after the frequency domain forming to a subcarrier so as to acquire a frequency domain signal after subcarrier mapping; and carrying out inverse Fourier transform on the frequency domain signal after subcarrier mapping so as to acquire a time domain signal.

Description

technical field [0001] This patent application relates to wireless communication technology, in particular to a communication processing method, a processor and a communication device. Background technique [0002] In future wireless communication systems, application scenarios such as high frequency, machine type communications, and the Internet of Things put forward higher requirements on the cost and energy consumption of devices. The selection of the device has a great correlation with the waveform signal, for example, the peak-to-average power ratio (PAPR) of the waveform signal affects the selection of the device. If the peak-to-average ratio of the input waveform signal is high, the D / A conversion and power amplifier devices are required to have a large dynamic range, otherwise it will cause signal distortion and affect system performance. Large dynamic range D / A conversion and power amplifier devices have high power consumption, low energy efficiency, and relatively...
