In this paper, we aim at analyzing the characteristic of neuronal population responses to instantaneous or time-dependent inputs and the role of synapses in neural information processing. We have derived an evolution equation of the membrane potential density function with synaptic depression, and obtain the formulas for analytic computing the response of instantaneous re rate. Through a techni...

Delay-Hopped Transmitted-Reference(DHTR) is an attractive scheme for Ultra-wideband(UWB) systems. It relieves the channel estimation and the synchronization problems, which simplifies the UWB system. This paper presents a platform developed at Delft University of Technology. The purpose of the platform is to supply a hardware environment to implement DHTR UWB components. It can emulate real UWB...

In wireless networks, an essential step for precise range-based localization is the high-resolution estimation of multipath channel delays. The resolution traditional delay algorithms inversely proportional to bandwidth training signals used probing. Considering that typical have limited bandwidth, using these often leads poor performance. To mitigate constraints, we exploit multiband and carri...
