| 摘 要： | 从提高频谱利用率和满足FCC辐射掩模规定的角度出发,采用频域反推和时域正交综合相结合的设计方法,利用扁长椭球波函数(PSWF)来生成脉冲基。在此基础上,应用基于有限项PSWF脉冲基的正交综合来优化设计UWB成形脉冲。仿真结果表明该算法设计的脉冲不仅能很好地满足FCC辐射掩模的要求,而且具有较好的频谱利用率。

| Abstract: | A novel ultra-wideband (UWB) pulse design algorithm combining the methods of spectrum analysis and orthogonal basis synthesis in time domain is presented to improve the spectrum utilization efficiency and conform the federal communications commission (FCC) emission mask constraint. UWB pulse can be obtained by orthogonal synthesis of finite number of prolate spheroidal wave function (PSWF) pulse basis,which matching FCC emission mask. The simulation results show that the pulse designed by this algorithm can... |
