| 摘 要： | 基于幂函数的带枝Schmidt正交化，给出一类可用于多元调制超宽带（UWB）无线通信系统的正交脉冲波形。这类正交脉冲波形克服了Hermite正交脉冲波形持续时间长短不一致的缺点，且有比Hermite正变脉冲波形频谱利用率高的特点。还从时域和频域分析了这类正交脉冲波形的特性。

| Abstract: | A new class of orthogonal pulse waveforms for ultra wideband communications is given here band-width not as Hermite orthogonal pulse waveforms, and their spectrum possess almost the same time-width and utilization is higher than Hermite orthogonal pulse waveforms. The performance of the orthogonal pulse waveforms is also analyzed in time domain and frequency domain. |
