Abstract

The invention discloses a method for measuring modulation quality parameters based on software radio technology and a system. According to the invention, an original time-domain signal with no demodulation and filtering is acquired through a sampling device, and a sampling value sequence is inputted into a general purpose computation device. In the general purpose computation device, a software analysis module, which corresponds to the communication standard and is used for measuring the modulation quality parameters, is used for executing a digital signal processing algorithm premade by a program to process the sampling value sequence that the sampling device outputs so that modulation quality parameter results of the measured signal are obtained. Based on the same test platform, the method for measuring the modulation quality parameters based on software radio technology and the system are capable of achieving measurement of modulation quality parameters of various different communication standards, can extend the functions of existing equipment, reduce measurement costs and improve measurement capability, and help to improve the measuring accuracy of the modulation quality parameters.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and system for measuring modulation quality parameters based on software radio technology. Background technique [0002] Mobile communication technology is the most widely used and fastest growing information technology in the world today. In order to meet different communication requirements, various communication standards have emerged. Modulation quality parameters are used to reflect the quality of communication signals and directly determine the bit error rate of communication systems. Therefore, in the measurement of communication signals of various mobile communication standards, modulation quality parameters are the focus of measurement and detection work. [0003] The demodulation of the traditional digital modulation signal is completed with a dedicated demodulation chip, but this approach leads to a relatively single type of signal that the sys...
