摘要
给出一种基于OFDM信号加窗设计的FPGA的具体实现方法,并通过无线传输信号在加窗前后带外能量大小的比较,说明该方法可以迅速地降低无线传输信号的带外能量,减少无线传输信号的带外辐射,降低无线信道污染以及对周围设备的干扰。
The article presents a implementation of windowing based on OFDM signals on the FPGA. By comparing the power without of band at before the windowing and after that, it shows the implementing method can make the power of without of band falling fast, reduce the radicalization of wireless signals without of band, and reduce the polluting on the wireless channel and disturbing on others equipment near it.
