Abstract

The invention relates to a peak-to-average ratio detection device. The peak-to-average ratio detection device comprises a detection control module, an instantaneous power detection module, an average power calculation module, a comparison sorting module and a data processing module; the detection control module is used for receiving a detection triggering signal and a configuration signal to generate a control signal according to the detection triggering signal and the configuration signal; the instantaneous power detection module is used for detecting instantaneous power of a detection signal according to the control signal; the average power calculation module is used for calculating the average power of the instantaneous power detected by the instantaneous power detection module; the comparison sorting module is used for sorting the instantaneous power obtained in detection to obtain the instantaneous power at the target sorted position; and the data processing module is used for calculating the peak-to-average ratio of the detection signal according to the average power and the instantaneous power at the target sorted position. The peak-to-average ratio detection device can detect the signal peak-to-average ratio generated when mobile equipment runs in real time and perfects the maintainable and detectable functions of the mobile communication equipment. The invention further relates to a peak-to-average ratio detection method and mobile communication equipment.

Description

technical field [0001] The present invention relates to the technical field of mobile communication digital signal processing, in particular to a peak-to-average ratio detection device and method, and also to a mobile communication device. Background technique [0002] Peak to Average Power Ratio (PAPR) is defined as the ratio of the peak power of the signal to the average power during a period of detection. In the industry, the peak-to-average ratio at which the occurrence probability of the peak-to-average ratio is less than 0.01% is usually used as the peak-to-average ratio of the detection signal, and the maximum value within the detection period is used as the reference index. The peak-to-average ratio is too high, which means higher instantaneous power. Because the linear region of the power amplifier is limited, large instantaneous signals will enter the nonlinear region of the power amplifier, which will cause the signal to be nonlinearly distorted, resulting in sig...
