| 摘 要： | 针对基带传输中的码间串扰问题，提出了基于椭圆球面波函数的基带传输系统设计方法。基带传输波形采用频带近似有限、持续时间为一个码元长度的椭圆球面波函数，根据基带传输系统的传输速率、码元持续时间、传输带宽等系统要求设置椭圆球面波函数的参数，通过构建椭圆球面波函数积分方程、数值求解和特征值排序等步骤完成基带传输波形设计。该方法不仅可有效提高基带传输系统的抗干扰能力，同时也使系统具有较好的功率利用率。

| Abstract: | For the question of intersymbol interference in baseband transmission system,a new design method based on Prolate Spheroidal Wave Functions(PSWF) is proposed.The baseband waveform is designed by using PSWF which lasts for one symbol interval and is approximately bandlimited in frequency domain.The PSWF's parameters can be set according to the data rate,the symbol duration and the bandwidth of the baseband system.The waveform design can be done through constructing integral equation,solving numerical equatio... |
