一种宽频认知无线电感知模块中PCI与上位机交互通信模块的改进方案

In order to improve the reliability of the sensing data of the wideband cognitive radio communication platform, an improved scheme of the PCI and PC communication module in the broadband cognitive radio sensing module is presented in this paper. Based on the existing interactive communication module, a new data communication module, a data buffering module based on FIFO, an encapsulation and analysis module are reconstructed. At the same time, the data processing module is optimized to improve the response of the communication system Speed, reducing the data packet loss rate. Experiments show that the proposed scheme can effectively improve the communication capability and anti-jamming capability of the wideband cognitive radio communication platform in the high-speed frequency hopping environment, which meets the system design requirements.
