摘要
采用GNU Radio技术及与其配套的硬件前端USRP设计和实现了230 MHz软件无线电多通道主站电台。该主站电台在调制方式上与现有无线电台设备全面兼容,覆盖了整个电力系统230 MHz全双工频段,可以同时在多个频点以不同的速率和调制方式与不同制式的从站电台进行双工通信。所提出的方案可以充分利用230 MHz无线频率资源,增加终端接入数量,提高通信系统组网的灵活性和可靠性,同时有效降低维护和升级的成本。
A multi-channel master radio station is designed and realized with GNU Radio and its associated device Universal Software Radio Peripheral(USRP) in this paper. The master radio station is all-around compatible with existing radio stations, covering 230MHz full-duplex frequencies, running at multi-frequencies simultaneously and carrying on full-duplex communications in different rates and modulation modes. The solution in this paper can take full use of the 230 MHz wireless frequency resource, increase the terminal access number, improve the reliability and flexibility of the communication system, and effectively decrease the cost of maintenance and upgrade at the same time.
