摘要
提出一种基于Parks-McClellan算法设计超宽带脉冲的方法,将脉冲设计等效为切比雪夫函数逼近问题。设计方法简单灵活,可满足各种幅频特性要求。Matlab仿真结果表明所设计脉冲的功率谱充分满足FCC频谱掩模要求并且频带利用率较高。
Present a new Ultra-wideband(UWB) pulse design method based on Parks-McClellan algorithm,which renders the pulse design problem equivalent to a Chebyshev function approximation problem.The method is simple and flexible to meet varied request.Simulation illuminate that the resulting pulses not only meet Commission(FCC) UWB mask but also optimally exploit the allowable the power spectral constraint of Federal Communications bandwidth and power.
