Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and device for detecting a wireless channel. Background technique [0002] In recent years, with the vigorous development of wireless communication and Internet technology, broadband multimedia wireless communication has been applied more and more. It is estimated that in the next 10 years, the capacity of wireless communication systems will need to increase by 1000 times to meet the increasing demand for wireless communication, and the wireless spectrum resources are limited, which drives us to further study the characteristics of wireless channels and adopt some new wireless communication technologies. More efficiently and fully utilize the potential capacity of the wireless channel. For example, for the subsequent evolution of the next-generation mobile communication system LTE-Advanced, it is necessary to break through the application dif...

Problems solved by technology

[0003] At present, the field of research on wireless channel characteristics still relies heavily on foreign wireless channel detectors or multiple instruments such as radio frequency (RF) signal transmitters, spectrum analyzers, network analyzers, GPS receivers and / or rubidium clocks to build complex wireless channels. Channel test system, these foreign instruments and equipment are not only extremely expensive (usually costing millions of yuan), but also have limited wireless channel detection signal bandwidth, channel detection system settings are not flexible enough, and do not have the ability to recognize and adapt to the wireless environment , bulky, not suitable for portable use in special environments (such as subway tunnels, indoors), limited channel characteristic analysis capabilities, and many other shortcomings
