针对通用接收机的中频信号输出，设计了中频信号采集、中频信号处理和高速数据传输硬件系统，应用于无线电监测系统。
For the snke of radio surveillance we design the hardware system with the function of IF data sampling, IF data processing and high speed data transferring.
由于认知无线电系统可能工作在非常宽的频带内，而且频谱一般不连续，所以数据传输方式必须能够自适应这种特性。
As cognitive radio system may work in very large bandwidth, and the spectrum is generally not continuous, so the data transmission must be adaptive to this feature.
