Burst Impulse Radio Communication with the Aid of Non-Coherent Methods

Burst communication is an important data transmission mode in wireless sensor network (WSN). Impulse radio ultra-wideband (IR UWB), which is a desired candidate of the physical layer of WSN, has been widely investigated. However, synchronization and timing recovery of coherent method requires a relative large system cost, which may constrain the widely use of impulse system. In this paper, we propose a coherent communication strategy while using non-coherent way to deal with the synchronization issue. This strategy can achieve a fast acquisition and precise timing with lower complexity, making the burst IR communication become promising in wireless sensor network.
