Problems solved by technology

[0005] Therefore, when objective evaluation criteria are used in actual testing, if only the signal-to-noise ratio / frame error rate / block error rate / packet error rate / bit error rate are used as the evaluation criteria for the evaluation of the receiving quality of the digital communication system, there will be incomplete evaluation. place
For example, in the case of control information errors, it is impossible to accurately analyze the receiving quality of the digital communication system

Abstract

The invention discloses a device for evaluating receiving quality of a digital communication system, which comprises a receiving processing unit, a receiving information resolving unit and a receiving quality evaluation unit, wherein the receiving processing unit is used for performing synchronization, decoding and error rate calculation on the receiving data of a receiving end of the digital communication system, and outputting synchronous mark and error rate; the receiving information resolving unit is used for judging the error type of the receiving data which finish synchronization and have error codes according to the synchronous mark and error rate output by the receiving processing unit; and the receiving quality evaluation unit is used for evaluating the receiving quality of the receiving data according to at least one of the error type, the error rate and the synchronous mark. The device can accurately and comprehensively evaluate the receiving quality of the digital communication system under the condition of different errors, and solves the problem of evaluation one-sidedness of the receiving quality in the prior art. The invention also provides a method for evaluating the receiving quality of the digital communication system.

Description

technical field [0001] The invention relates to the technical field of digital information transmission, in particular to a receiving quality evaluation device and method of a digital communication system. Background technique [0002] When evaluating the transmission quality of a digital communication system, traditional methods have two evaluation criteria, subjective and objective. The subjective evaluation standard refers to observing the received content, such as an image, within a certain period of time, and the time when an obvious error occurs is used as the evaluation standard for the image quality. The objective evaluation standard is to use signal-to-noise ratio / frame error rate / block error rate / packet error rate / bit error rate as the evaluation standard for receiving quality. For example, in some standards, the bit error rate BER<10E-5 is used as the qualified standard. [0003] However, according to communication theory, it can be known that the usual forma...
