Increasing the Reliability of Concurrent UWB Transmissions over Complex Channels

Research output: Contribution to conferencePosterpeer-review

Abstract

Due to hardware limitations and legal restrictions, very few frequency channels are usable when developing applications based on ultra-wideband systems. As this hinders the adoption of this increasingly popular technology, the IEEE 802.15.4 standard introduces the concept of complex channels in order to create multiple orthogonal channels within the same frequencies. However, concurrent transmissions on different complex channels are known to be unreliable and lead to a high packet loss. In this poster, we propose a novel method to increase the reliability of concurrent transmissions on complex channels by altering the radio’s clock frequency offset. Preliminary results show that the packet reception rate of concurrent transmissions on several complex
channels remains close to 100 % when increasing the relative clock frequency offset of the devices by more than 5 ppm.
