摘要
提出了一种基于OVSF码的混合OVSF-TH-UWB通信系统,并设计了相应的接收机相关掩模。通过性能分析和仿真实验表明,OVSF-TH-UWB系统能有效地提高其抗加性高斯白噪声性能以及抗多用户干扰能力,而且其性能优于2PPM-TH以及DS-UWB。
A hybrid OVSF-TH-UWB based OVSF-code was proposed, and a corresponding correlation mask was de- signed. Both performance analysis and simulation results prove that OVSF-TH-UWB system can effectively reduce the multi-users-interference and Gaussian noise interference, and its performance is better than those of 2PPM-TH and DS-UWB system.
