| 摘 要： | 针对美国FCC关于超宽带传输系统提出的辐射掩蔽特性,提出了一种基于正弦高斯组合的UWB脉冲波形设计新方案。以一组正弦高斯脉冲为基函数,利用最小均方误差准则(LSE)选取加权系数对基函数进行线性组合,通过调整基函数的载波频率和脉冲形成因子,对波形进一步优化。分析了TH-PPM UWB多用户系统的误码率性能。仿真结果表明,与高斯二阶微分脉冲、随机系数组合脉冲相比,基于正弦高斯组合脉冲具有更高的频谱利用率,误码性能更优。 |

| Abstract: | Aimed at the emission mask property of ultra wideband(UWB)system proposed by federal communications commission(FCC),a novel pulse waveform design method for UWB communication based on combination of the sinusoid Gaussian pulse is presented.The sinusoid Gaussian pulses are chosen as basis functions.The weighting coefficients based on least square error(LSE) are made certain which acted as linear combination coefficients of basis functions.The waveform is further optimized by tuning carrier frequency and shaping factors of the basis functions’ parameters.The bit error rate(BER) performance of the TH-PPM UWB pulse is analyzed in a multi-user environment.Compared with the second derivative Gaussian pulse and random coefficient combination pulse,the simulation results show that the pulse designed based on combination of the sinusoid Gaussian pulse has higher spectral utilization efficiency and better bit error rate(BER) performance. |
