本文提出了一种新的长球面波函数作为脉冲无线电（超宽带）通信中使用的脉冲形状。这些函数类产生正交脉冲，并且具有恒定的脉冲宽度，而不管脉冲顺序。这是一个重要的属性，因为它消除了符号间干扰。一个M元通信系统被认为是采用这些脉冲，并提出了使用自伴算子的本征函数形式的这些脉冲的产生。它也表明，这些脉冲是适合于使用在脉冲位置调制（PPM）超宽带（UWB）通信系统。
In this paper novel prolate spheroidal wave functions are proposed as pulse shapes for use in impulse radio (ultra-wideband) communications. These classes of functions yields orthogonal pulses and have a constant pulse width regardless of the pulse order. This is an important property since it eliminates inter-symbol interference. An M-ary communications system is considered that employs these pulses, and the generation of these pulses using the eigenfunction form of a self-adjoint operator is proposed. It is also shown that these pulses are suitable for use in pulse position modulation (PPM) ultra wideband (UWB) communication systems.
