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.
