摘 要: 在实现一种基于能量检测的脉冲超宽带(IR-UWB)通信系统的基础上对其相应的同步过程进行了深入分析。论证了在一定环境条件下上述系统的最佳传输模式,包括传输速率和数据帧结构,并得出在此模式下系统的有效性和可靠性可达到最优折中。通过实际测量对系统性能进行了测试,验证了最佳传输模式的实用性。结果表明,最佳传输模式的引入可以作为系统设计的重要参考。 An impulse radio-ultrawideband (IR-UWB) communication system was proposed and realized based on the energy detection, and the related synchronization process was investigated on the pulse and frame levels. An optimal transmission mode under the typical indoor environment was described to get the best trade-off between the reliability and the effectiveness of the proposed mode. Meanwhile, the reference frame structure and transmission rate in this optimal mode under certain environments were given. System performance was tested be practical experiments, and the results showed the practicality of the optimal transmission mode to the IR-UWB system design.
