超宽带高速数据传输技术研究

摘要

为了解决超宽带（ UWB）高速数据传输中的硬件处理速度瓶颈、码间干扰和多径影响等问题，可采用多个伪码并行调制传输的方法，该方法可以有效提高超宽带系统的传输速率，降低码间干扰和实际工程处理难度。经过对多伪码并行超宽带信号的调制发射、接收解调的性能分析，并通过实物试验，验证了其工程可实现性。与DS-UWB系统相比，在相同的传输带宽下，提高了信息速率，但这是以设备的复杂度增大为代价的。%To address the issues such as hardware processing speed,inter-symbol interference and multipath effect in ultra wide-band( UWB) high speed data transmission,the method of multiple parallel pseudo-code modulation and transmission can be adopted, which can effectively enhance the transmission rate of UWB system and reduce the inter-symbol interference and practical engineering processing difficulty.Through an analysis on the performance of multiple parallel pseudo-code modulation,transmission,receiving and demodulation of UWB signal as well as practical test,the method�s engineering feasibility is verified.Compared with DS-UWB system,the information rate under the same transmission bandwidth is improved.However,it is at the cost of an increase of equipment complexity.
