Signal processing method, device and equipment and readable storage medium

Abstract

The embodiment of the invention provides a signal processing method and device, equipment and a readable storage medium, and the method comprises the steps: responding to a first signal received in a first time slot, judging whether the first signal meets a first preset condition, and transmitting a synchronization signal in a second time slot if the first signal meets the first preset condition, the second time slot is a time slot which is after the first time slot and is adjacent to the first time slot. If the first signal does not meet the first preset condition, judging whether the first signal meets a second preset condition or not; and if the first signal satisfies a second preset condition, transmitting a stop signal in a second time slot. The first preset condition comprises that the first signal is a synchronization signal, the second preset condition comprises that the first signal is not a service signal, the synchronization signal is a synchronization frame whose time length is less than a preset time slot time length, and the stop signal comprises a synchronization frame whose time length is equal to the time slot time length, so that the synchronization signal is different from other signals in time length; the method can avoid the phenomenon that the synchronization signal interferes with the service signal.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a signal processing method, device, equipment and readable storage medium. Background technique [0002] In the communication system, during the process of transmission, forwarding and receiving, the signal will be affected by environmental noise, co-channel interference and the hardware of the device itself (such as phase-locked loop, voltage-controlled crystal oscillator, etc.), which often leads to the failure of normal establishment of business signals . Among them, co-channel interference includes the same frequency and different waves caused by the synchronization frame. Taking the repeater E1 as an example, the received synchronization frame interferes with the new service signal on the same frequency, which makes E1 unable to receive and forward the service signal normally. It can be seen that how to avoid co-channel interference is an important way t...

Problems solved by technology

[0002]In the communication system, during the process of transmission, forwarding and receiving, the signal will be subject to environmental noise, co-channel interference and the hardware of the equipment itself (such as phase-locked loop, pressure Controlled crystal oscillator, etc.) will often cause the business signal to fail to be established normally

Among them, co-channel interference includes the same frequency and different waves caused by the synchronization frame. Taking the transponder E1 as an example, the received synchronization frame interferes with the newly accessed service signal on the same frequency, which makes E1 unable to receive and forward the service signal normally.
