The embodiment of the invention discloses a terminal signal data synchronization processing method and device, and the method comprises the steps: obtaining a preset number of sign bits in a time domain signal transmitted by a terminal, taking the sign bits as a unit of data source for frequency domain conversion, and obtaining terminal frequency domain data; performing frequency domain mapping, time domain conversion and frequency domain conversion on the local DMRS sequence to obtain DMRS frequency domain data; performing correlation calculation on the terminal frequency domain data and theDMRS frequency domain data to obtain a correlation result, and performing time domain conversion on the correlation result to obtain correlation time domain data; and determining each DMRS sign bit according to the related time domain data, determining an initial bit of each time slot according to each DMRS sign bit, and realizing data synchronization with the terminal signal according to the initial bit of each time slot. The initial bit of each time slot can be quickly determined according to each DMRS sign bit, data synchronization between a non-signaling comprehensive test instrument product and a terminal is realized, the operand is reduced, the calculation complexity is greatly reduced, and the synchronization speed is improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a data synchronization processing method and device for terminal signals. Background technique [0002] The non-signaling comprehensive tester products in 5G NR (New Radio) technology are relatively cutting-edge products, and the plans of major manufacturers have not been announced, and there are few relevant papers for retrieval. [0003] In the existing 5G NR technology, there is no synchronization process between the non-signaling comprehensive tester product and the terminal, and there is no interaction between signaling. Since there is no synchronization process between the non-signaling comprehensive tester and the terminal, it is necessary to detect the starting position of the time slot of the terminal signal in an effective way before performing subsequent measurement functions. [0004] At present, it is still impossible to detect the starting position o...
