| 摘 要： | 为了提高系统的单位频带利用率，基于时限椭圆球面波函数提出了一种高效正交脉冲设计方法。脉冲设计频段被划分为多个相互交叠的子频带，基于频〖CD*2〗时域波形设计方法，各子频带分别求解带通时限椭圆球面波函数。通过正交化方法构建时域正交脉冲，所设计的正交脉冲在子频带内频谱相互混叠，相邻子频带内频谱相互交叠。理论分析及仿真结果表明，正交脉冲在频域上具有较好的能量聚集性，用于信息传输时，通信系统的单位频带利用率极限值可达到2 Baud/Hz。 |

| Abstract: | For improving system bandwidth efficiency,an orthogonal pulses designing method with high efficiency based on time-limited prolate spheroidal wave functions is proposed.Frequency band is divided into multiple sub-bands which are overlapped in frequency domain.Bandpass and time-limited prolate spheroidal wave functions are derived from each sub-band based on the frequency-time domain pulse designing method.Orthogonal pulses are constructed by an orthogonalization method.The pulses' spectrum is mixed in the s... |
| Keywords: | communication bandwidth efficiency prolate spheroidal wave function(PSWF) orthogonal pulse |
