| 摘 要： | 由于物理实现因素的影响,信息传输系统的频带利用率极限值一般降至1.8Baud/Hz以下。针对该问题,提出了一种传输波形设计方法。基于椭圆球面波函数设计时域正交脉冲,通过正交脉冲传输信息。通过理论分析,系统频带利用率的极限值可达到2Baud/Hz,且可快速接近奈奎斯特速率,又因椭圆球面波函数的能量聚集特性,可有效提高信息传输系统的功率利用率。

| Abstract: | For physical realization factors,the bandwidth efficiency of the baseband system is always below 1.8Baud/Hz.For this issue,a design method of waveform is proposed.Orthogonal pulse is constructed based on Prolate Spheroidal Wave Functions (PSWF).Information is transmitted by PSWF pulses.Theory analysis shows that the bandwidth efficiency can be fast close to 2Baud/Hz.Good energy concentration of the PSWF is very important for improving the power efficiency of baseband system. |
