我们提出了一种用于生成用于脉冲无线电通信的修正埃尔米特多项式函数的电路。开发了不同阶脉冲的同时生成，降低了电路复杂性。脉冲是通过对 Hermite 多项式进行修改来产生的。脉冲具有正交性的特性，并且不会显着依赖于脉冲阶数或在发射机或接收机天线的微分效应下改变其脉冲宽度和脉冲带宽。通过计算机模拟与传统脉冲位置调制进行比较，显示了通过正交脉冲调制应用于多用户系统的这些脉冲的有用性。
We propose a circuit for generation of modified Hermite polynomial functions for use in impulse radio communications. Simultaneous generation of pulses of differing order is developed, reducing circuit complexity. Pulses are produced by applying modifications to Hermite polynomials. Pulses have the properties of orthogonality and not changing their pulse width and pulse bandwidth significantly dependent on pulse order, or under the differentiation effect of the transmitter or receiver antenna. The usefulness of these pulses applied to a multi-user system by orthogonal pulse modulation is shown by comparison with conventional pulse position modulation by computer simulation.
