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 application of the invention discloses a communication processing method, processor and communication equipment. The communication processing method comprises: performing orthogonal quadrature amplitude modulation (OQAM) on data to obtain a QAM modulated symbol in a time domain; performing a Fourier transform on the QAM modulated symbol in the time domain to obtain a frequency domain signal generated after the Fourier transform; performing frequency domain forming on the frequency domain signal generated after the Fourier transform to obtain a frequency domain signal generated after the frequency domain forming, wherein a conjugate and symmetric frequency domain signal is removed to form the frequency domain signal generated after the frequency domain forming; mapping the frequency domain signal generated after the frequency domain forming to a subcarrier to obtain a frequency domain signal mapping to the subcarrier; and performing an inverse Fourier transform on the frequency domain signal mapping to the subcarrier to obtain 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...
