Embodiment Construction

[0043] In order to explain in detail the technical solutions and effects of the digital signal detection method of the present application, the relevant content will be explained below.

[0044] Taking digital signals such as DMR (Digital Mobile Radio, digital mobile radio) or PDT (Public Digital Trunking, police digital trunking standard) signals as an example, in the traditional DMR / PDT synchronous detection scheme, the baseband signal is generally digitally demodulated. The best way is to perform synchronous detection to determine whether there is a useful signal in the current channel. Since the synchronous detection takes a long time (a single DMR / PDT superframe is 360mS, it takes a long time to determine whether there is a signal), so the radio frequency in power saving mode The open time of the circuit is longer, which affects the power saving effect. In addition, DMR / PDT is divided into 2 time slots, and the length of each time slot is 30mS. Therefore, the waveform of...

Abstract

The invention provides a digital signal detection method, a digital signal detection device, a storage medium and computer equipment thereof, wherein the method comprises the steps of: extracting a signal quality signal in received digital signals, comparing the voltage of the signal quality signal with the pre-set voltage threshold value of the signal quality signal, and performing synchronous detection when the voltage of the signal quality signal is lower than the voltage threshold value of the signal quality signal; and, not performing synchronous detection when the voltage of the signal quality signal is higher than the voltage threshold value of the signal quality signal. When the signal quality voltage value is compared with the voltage threshold value, whether synchronous detectionis started or not is further selected; the time of synchronous detection having relatively long detection time can be reduced; the running time of a signal receiving device when detection is carriedout can be reduced; and thus, the electric energy consumption can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a digital signal detection method, device, computer equipment and readable storage medium. Background technique [0002] Digital communication equipment is a communication equipment that uses digital signals as carriers to transmit information, or uses digital signals to digitally modulate and then transmit carrier waves. It needs to modulate and demodulate baseband signals. It has strong anti-interference ability, error controllability, easy encryption and Easy to combine with modern technology and other advantages. Moreover, with the rapid increase of people's demand for various communication services, digital communication is rapidly developing in the direction of miniaturization, intelligence, high speed and large capacity. [0003] In the traditional technology, the digital signal detection in the digital communication equipment is to directly and synchronously detect...
