Abstract: This paper presents a novel receiver windowing algorithm to combat the strong Narrowband Interference(NBI) in Ultra- Wideband(UWB) communication systems. The windowing is proposed for Multi-Band Orthogonal Frequency Division Multiplexing(MB-OFDM) UWB system which adopts the Zero Padding(ZP) scheme. Compared with other NBI cancellation algorithm, it has lower design complexity and need not NBI detection. Experiment of Packet Error Rate(PER) under different strong NBI sources verifies the effectiveness and feasibility of receiver windowing.

摘要： 提出一种能抵抗超宽带系统中强窄带干扰的接收端加窗算法，它适用于多带正交频分复用(MB-OFDM)超宽带通信系统中采用的零值填充机制。相对于其他抗窄带干扰算法，接收端加窗算法具有算法复杂度低、无须对窄带干扰进行预估计等优点。在不同强窄带干扰源下的系统无线数据包错误率的仿真测试验证了该算法的有效性和可行性。
