摘要 首次提出了适用于零值填充多带正交频分复用系统(OFDM)的接收端加窗处理方法.该算法可以有效地抵抗系统中的强窄带干扰,提高OFDM系统各子载波上的信号干扰比.相对于其他的抗窄带干扰算法,该算法可以降低均衡器的复杂度,并且不需要对窄带干扰的频率和带宽进行预估计.在硬件实现上,加窗算法只需要在系统的接收端进行简单的加法和乘法运算,因此它很有可能成为未来工业界一种新兴的抗干扰技术.通过在不同强窄带干扰源下的系统无线数据包错误率仿真测试,验证了该算法的有效性和可行性. A novel receiver windowing algorithm is presented, it adopts the zero padding (ZP) scheme and is specially adapted for the Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) Ultra-Wideband (UWB) systems. The windowing algorithm can not only resists the strong Narrowband Interference (NBI) in Ultra-Wideband (UWB) communication systems, but also decrease the design complexity of equalizer. Compared to other NBI cancellation approaches, the proposed receiver windowing technique has its unique advantage of low design complexity without NBI detection. Simulation test of the packet error rate (PER) for different strong NBI sources verifies the effectiveness and feasibility of the proposed receiver windowing algorithm.
