摘要
根据8阵元智能天线原理,给出一种基于软件无线电思想的数字波束形成系统。分别对该系统的射频处理和数字处理两部分进行了讨论。在射频处理部分采用带通采样直接对射频信号进行数字化,数字处理部分则采用可编程数字器件FPGA和DSP实现。实验结果表明,该系统满足波束形成的要求,并具有良好的通用性和灵活性。
A digital beamforming system based on software radio is presented according to the principle of 8 - sensor smart antennas. Radio processing and digital processing of the system are discussed respectively. In radio processing, radio signal is directly digitized by bandpass sampling, and digital processing is implemented by programmed digital devices. The result of experiment shows that the system meets the requirement of digital beamforming. The system has flexible and general characteristics.
