Abstract

A peak-to-average ratio detection device, comprising: a detection control module, configured to receive a detection trigger signal and a configuration signal, to generate a control signal according to the detection trigger signal and the configuration signal; an instantaneous power detection module, configured to generate a control signal according to the The control signal detects the instantaneous power of the detection signal; the average power calculation module is used to calculate the average power of the instantaneous power detected by the instantaneous power detection module; the comparison and sorting module is used to sort the detected instantaneous power to obtain The instantaneous power at the target sorting position; and a data processing module, configured to calculate the peak-to-average ratio of the detection signal according to the average power and the instantaneous power at the target sorting position. The peak-to-average ratio detection device can detect the signal peak-to-average ratio in real time when the mobile device is running, and improves the maintainable and measurable function of the mobile communication device. The invention also relates to a peak-to-average ratio detection method and a mobile communication device.

Description

technical field [0001] The 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 signal peak power to average power within a period of detection. In the industry, the index at which the peak-to-average ratio occurs with a probability 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 a reference index. High peak-to-average ratio means higher instantaneous power. Due to the limited linear region of the power amplifier, large instantaneous signals will enter the nonlinear region of the power amplifier, causing the signal to be nonlinearly distorted, resulting in signal distortion and spectrum expansion, resulting in a serious decline in system...
