摘要

提出了一种基于频带编码的频率自适应检测与避免(DAA)设计方法，用于窄带干扰抑制。高斯导数脉冲由于其直流分量为零、易于产生和满足美国联邦通信委员会(FCC)室内外频谱掩模的特点，被认为是超宽带(UWB)原始脉冲。仿真结果表明，该方法能够提供稳定的超宽带正常发射功率，具有较高的传输效率和不间断通信能力。自适应脉冲在WLAN受害系统的频带中产生−40dB陷波深度。此外，自适应脉冲产生与FCC频谱掩模匹配的任意频谱陷波。

Frequency adaptive DAA design based on frequency band encoding

A frequency adaptive detect and avoid (DAA) design method based on frequency band encoding is presented for narrow band interference suppression. Gaussian derivative pulse is considered as the ultra-wideband (UWB) original pulse because of its characteristics of zero DC component, easy generation and meeting with the Federal Communications Commission (FCC) indoor and outdoor spectral mask. Simulation results show that the proposed DAA method can provide stable UWB normal transmit power, have high transmission efficiency and make uninterrupted communication. The adaptive pulses create −40dB notch depth in the frequency band of the WLAN victim system. Furthermore, the adaptive pulses produce arbitrary spectral notches matching the FCC spectral mask.
