| 摘 要： | 从PSWF脉冲的高能量聚集性和频谱灵活可控性入手,提出了一种满足FCC掩膜要求且具有高频谱利用率的多频带正交PSWF脉冲组设计方法,并将其应用于多用户、多进制的PPM-UWB系统中。理论计算了该系统的符号差错率公式,与使用单一PSWF脉冲UWB系统进行了性能比较。仿真结果表明,基于多频带正交PSWF脉冲组的UWB系统能够有效克服多用户干扰,从而使系统的误码性能得到显著提高。 |

| Abstract: | In this paper,we proposed a multiband orthogonal PSWF pulse set design method.The designed pulse set has a high spectrum utilization efficiency while meeting the FCC spectral mask without frequency shifting or additional filtering.Based on this,a M-ary PPM modulation scheme using the orthogonal pulse set is developed.In this scheme each user is assigned a different orthogonal PSWF pulse.An analytic expression of the SER performance for the scheme is derived theoretically.Simulation results show that the pro... |
