Problems solved by technology

[0012] In recent years, with the widespread deployment and application of synchronous networks, the construction acceptance of synchronous network sites and the application scenarios of continuous monitoring and maintenance of synchronous networks have gradually increased. MTIE is frequently used as an important indicator for evaluating the quality of synchronous signals. The data is highly traversed, and the calculation complexity is high, which poses higher challenges to the real-time calculation and storage capacity, and requires an efficient acceleration algorithm to solve the calculation bottleneck problem

Abstract

The invention discloses a maximum time interval error calculation method. MTIE acceleration calculation is carried out through a classical algorithm and quantum search algorithm mixed calculation framework, the classical algorithm is optimized by adopting a minimum index progressive strategy, parallel acceleration is carried out by utilizing quantum calculation entanglement properties, and a Grover algorithm is improved, so that the time and the complexity of MTIE calculation are remarkably reduced; on the other hand, the invention provides a maximum time interval error calculation system comprising a sampling module and a processing module. According to the maximum time interval error calculation method and system provided by the invention, minimum value and maximum value search acceleration is realized, the number of traversal times is reduced, the MTIE calculation complexity is reduced, and the calculation speed is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for calculating a maximum time interval error. Background technique [0002] In measurement and control systems and communication networks, it is necessary to measure the stability of frequency or time synchronization signals. The Maximum Time Interval Error (hereinafter referred to as "MTIE") is a key measurement index for evaluating synchronization drift performance. MTIE The calculation includes two parts: one is the sampling of the time error sample data, and the other is the processing of the sample data. Through a series of algorithms, the MTIE values ​​corresponding to several observation windows are calculated. The advantages and disadvantages and complexity of the calculation method will directly It affects the confidence and efficiency of MTIE measurement. [0003] The calculation of MTIE is to obtain the synchronization error data by compari...
