Wireless signal transmitting and receiving method and system based on polling networking working mode

Abstract

The invention belongs to the technical field of wireless communication, and particularly relates to a wireless signal receiving and transmitting method and system based on a polling networking working mode, and the method comprises the steps: taking a universal software radio peripheral (USRP) as a unit to build each station in a wireless communication platform, and distributing a unique address code to each station in the platform; in the networking process, a universal software radio peripheral (USRP) of which the station type is a master station sends signals in sequence according to a preset polling list according to a set polling working mode, and other USRPs of which the station types are slave stations receive the signals and process the signals to obtain return parameters in the signals; and comparing the address code in the return parameter with the own address code, if the address code in the received signal is the same as the own address code, executing a reply action, otherwise, keeping silence. The problem that networking between existing data link communication platforms is difficult is solved, efficient network data communication between all network access units and real-time data processing, exchange and distribution between devices are achieved, and implementation is convenient.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a method and system for transmitting and receiving wireless signals based on a polling networking working mode. Background technique [0002] With the upgrading of communication systems, traditional communication methods are increasingly unable to meet the needs of modern information exchange. As an intermediary between sensors and sensors, sensors and information platforms, and information platforms and information platforms, data link communication adopts wireless network communication technology and communication protocols, and plays a role in data information exchange between airborne, road-based and ship-borne communication systems. Wide range of applications. Compared with foreign countries, my country's research on data link communication started late, and there are certain difficulties in the interconnection and intercommunication of informatio...
