Abstract

We propose a novel detection method for non-coherent synchronization in multi-access UWB impulse radio (IR) networks. It is designed to solve the IUI (Inter-User Interference) in particular the Near-Far scenario in the presence of concurrent UWB IR transmissions with multiple interfering transmitters, asynchronous transmissions and heterogeneous power levels, as can be found in ad-hoc networks. In such scenarios, the conventional synchronization method, which is based on correlating the received IR signal with a Template Pulse Train (TPT), does not always perform well. Our proposal has similar complexity as the conventional method. We evaluate its performance with the Line Of Sight (LOS) office indoor channel model proposed by the IEEE P802.15.4a study group and find that the improvement is very significant.

Time-division multiple access

Time-division multiple access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same transmission medium (e.g. radio frequency channel) while using only a part of its channel capacity.

Ultra-wideband

Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applications in non-cooperative radar imaging. Most recent applications target sensor data collection, precise locating, and tracking. UWB support started to appear in high-end smartphones in 2019. Ultra-wideband is a technology for transmitting information across a wide bandwidth (>500 MHz).

Radio resource management

Radio resource management (RRM) is the system level management of co-channel interference, radio resources, and other radio transmission characteristics in wireless communication systems, for example cellular networks, wireless local area networks, wireless sensor systems, and radio broadcasting networks. RRM involves strategies and algorithms for controlling parameters such as transmit power, user allocation, beamforming, data rates, handover criteria, modulation scheme, error coding scheme, etc.
