| 摘 要： | 基于完全互补码极好的相关特性,采用其作为扩频码,提出了基于完全互补码的DS-UWB系统模型.为了多个用户使用该系统,其中发射端采用码片移位方式实现.接收端则采用相关接收机解调用户信息.N路接收信号分别相关运算后叠加并进行判决,对前后码元的关联性使得系统性能有很大提高.在AWGN环境下和802.15.3a推出的UWB信道模型(CM2)下,对单用户和4用户情况下该模型的误比特率性能与采用Gold码和Walsh码时的性能进行了仿真分析.从仿真结果可以看出,采用完全互补码的DS-UWB系统性能有显著提高.

| Abstract: | The DS-UWB system model was founded based on the complete complementary code's characteristic,which the crosscorrelation function was zero,was introduced as the spread code for it to improve the performance in multiple access.The shift-and-add way based on complete complementary codes was applied in transmitter.The correlation receiver was employed to decode the intended user's information.Each received signals in paths make the correlation operation firstly,then added together and make a judge.The performa... |
