Description

technical field [0001] The invention relates to an airport wireless channel simulator for typhoon detection applications. The simulator is based on a CPU (Central Processing Unit, central processing unit) + FPGA (Field-Programmable Gate Array, Field Programmable Gate Array) architecture. (Peripheral Component Interface Express, bus and interface standard) completes data interaction, specifically involves the calculation of key parameters of the airport wireless channel simulator, data transmission and interrupt response, and the hardware simulation method of the channel fading model, which belongs to the field of wireless communication. Background technique [0002] my country is located on the west coast of the Northwest Pacific Ocean, and typhoons (a tropical cyclone in the Northwest Pacific Ocean) land very frequently. On average, 7 to 9 typhoons land on the mainland of China every year, causing casualties and direct economic losses. Therefore, typhoon prevention and disas...

Problems solved by technology

This combination of software and hardware architecture also ensures the real-time performance of the channel. Although the parallel interface can greatly improve the data transmission speed, the length of the parallel transmission line is limited. The increase of the length will increase the interference and make the data transmission more error-prone.

In the application scenario of typhoon detection, the requirements for data transmission are high, and the existing wireless channel simulator with a combination of software and hardware is not suitable. Therefore, it is necessary to find an airborne wireless channel simulator for typhoon detection applications. To provide support for various studies related to typhoon detection
