Abstract

The invention relates to a method for realizing frame synchronization processing aiming at a 5G synchronization signal missing situation, and the method comprises the following steps: acquiring data, performing coarse positioning, and preliminarily determining a time slot containing a downlink OFDM symbol; carrying out fine positioning, sliding related operation, and realizing downlink OFDM symbol synchronization through time domain characteristics of OFDM; carrying out FFT operation, taking time domain data and mapping the time domain data to a frequency domain; carrying out the frame synchronization, and determining the position of a frame header by positioning a downlink OFDM symbol containing a PDSCH reference signal. The invention further relates to a corresponding system and device, a processor and a computer readable storage medium. By adopting the method, the system, the device, the processor and the computer readable storage medium for realizing the frame synchronization processing aiming at the 5G synchronization signal missing condition, the frame synchronization in the state is realized by utilizing the characteristics of the reference signal; in the actual operation process, time domain characteristics of time division multiplexing, time domain characteristics of OFDM signals and the like are used for achieving downlink OFDM symbol synchronization in a software and hardware combined processing mode. A software and hardware combined processing mode is adopted, and frame synchronization under the condition of synchronous signal loss is realized through hierarchical processing.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to the field of signal measurement, and specifically refers to a method, system, device, processor and computer-readable storage medium for realizing frame synchronization processing for the absence of 5G synchronization signals. Background technique [0002] With the rapid development of communication technology, the fifth-generation mobile communication (5G), which is about to be commercialized, will be closely integrated with wireless mobile communication technology to form a new generation of ubiquitous mobile information network. Correspondingly, relevant supporting equipment such as signal analyzers, signal gain devices, etc. need to be upgraded. [0003] The above-mentioned devices need to achieve frame timing with the signal source as the first condition when they work. The SS / PBCH block is defined in the 5G frame structure as the corresponding physical signal / c...

AI Technical Summary

Problems solved by technology

However, for the 5G Test model signal given in the 3GPP protocol, the frame structure does not include SS / PBCH blocks. For this situation, the traditional solution is to connect a trigger line between the receiving end and the sending end, that is, both are in the triggered state

[0004]As far as the traditional method is concerned, it cannot solve the problem of the received Frame synchronization for 5G signals (such as Test model signals) that do not contain SS / PBCH blocks
