A Novel Receiver Structure for Time-Hopping UWB in Multiple Access Interference
Ultra-wide bandwidth technology (UWB) is proving to be a promising solution for high capacity, wireless multiple access systems. Described as Bluetooth on steroids, UWB provides extremely high data rate performance in multiple user applications. It will replace wires and cabling in commercial, industrial, educational and residential applications. In local and personal area networks (LAN/PAN), UWB will connect cellphones, laptops, PDAs, cameras and MP3 players. In the automotive space, UWB can be integrated with in-car service and entertainment as well as roadside info-stations. UWB will make collision avoidance-detection available to private motorists and heavy equipment operators.
Meanwhile it has been shown that multiple access interference significantly degrades the performance in these systems. Researchers at the University of Alberta have developed a novel receiver structure for detecting a time-hopping ultra-wide bandwidth signal in the presence of multiple access interference-plus-Gaussian-noise environments. This structure achieves better bit error rate performance compared with conventional matched receivers and meets or surpasses the performance of conventional UWB receivers for all values of signal-to-noise ratio and all values of signal-to-interference ratio, while still retaining a relatively simple receiver design structure.
- Improved bit error rate performance
- Increased performance under all operating conditions in interference
This invention will be of interest to companies that design and manufacture wireless communication systems.
