Description

technical field [0001] The invention relates to the technical field of analysis of wireless communication signals, in particular to a channelized high-precision real-time spectrum analysis method and system thereof. Background technique [0002] The current social demand for analysis of wireless communication signals is increasing, and the analysis requirements are getting higher and higher. Major foreign instrument manufacturers have invested huge manpower and material resources in the research and development of spectrum analyzers. [0003] Spectrum analyzer is an instrument for studying the spectrum structure of electrical signals. It is used to measure signal parameters such as signal distortion, modulation degree, spectral purity, frequency stability and intermodulation distortion. It can be used to measure certain components of circuit systems such as amplifiers and filters. It is a multi-purpose electronic measuring instrument; it can also be called frequency domain o...

Problems solved by technology

[0004] Generally speaking, after nearly 30 years of rapid development, domestic spectrum analyzers have reached the level of similar foreign products in displaying average noise level, phase noise, resolution bandwidth, advanced test functions and many other indicators. The detection range, detection sensitivity, storage and playback of spectrum information, and product integration are still insufficient, especially how to detect tiny signals hidden in noise under wide-band conditions
