研究了一种基于差分高斯脉冲线性组合的超宽带(UWB)无线通信脉冲无线电波形spila设计方法。根据整形因子和微分系数的扩频效应，提出了一种构造微分高斯脉冲的新方法。为了获得最佳的权系数，将基于最小均方误差(MMSE)和权系数计算的集成算法应用于信号构造。仿真结果表明，室内外线性组合UWB脉冲具有最佳的接近美国联邦通信委员会(FCC)发射掩模规则的限制能力，并且具有最佳的误码率(BER)和测距性能以及频谱利用率高、可控功率强、设计灵活等诸多优点。
Based on linear combination with differential Gaussian pulse, a designing impulse radio waveformspsila method for ultrawideband (UWB) wireless communications was investigated. According to the spread spectrum effect of the shaping factor and differential coefficient, a novel method on constructing differential Gaussian pulse was proposed. So as to gain the best weight coefficient, a integrated algorithm based on the minimum mean square error (MMSE) and weight coefficient calculation is applied to the signal construction. The simulation results show that the linear combined UWB pulse indoors and outdoors have the best ability of limit approach to the Federal Communications Commission (FCC) emission mask rule, and whatpsilas more, it has the best performance of bit error rate (BER) and ranging and many other merits, such as high rate of using spectrum, strong controllable power and flexible design, et al.
