【摘要】 基于幂函数的带核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正交脉冲波形频谱利用率高的特点。本文还从时域和频域分析了这类正交脉冲波形的特性。更多还原

【Abstract】 A new class of orthogonal pulse waveforms for ultra wideband communications is proposed based on the Schmidt orthogonalization. The orthogonal pulse waveforms given here possess almost the same time-width and band-width not as Hermite orthogonal pulse waveforms and their spectrum utilization is higher than Hermite orthogonal pulse waveforms. The performance of the orthogonal pulse waveforms is also analyzed in time domain and frequency domain.更多还原
