The pre-Rake scheme for pulse based ultrawideband (UWB) communications system is proposed in a standardized UWB channel model from IEEE 802.15 SG3a, which is based on …
UWB pulses are the unique labels of UWB systems. This paper investigates the role of pulse systematically and highlights the central position of the pulse in UWB systems. Four system …
Mobile communication channels are often modeled as linear time-varying filters or, equivalently, as time-frequency integral operators with finite support in time and frequency …
We present an efficient, low-cost implementation of time-hopping impulse radio that fulfills the spectral mask mandated by the FCC and is suitable for high-data-rate, short-range …
We study the correspondence between time-frequency and time-scale integral operators and determine the mapping between time-scale kernels and time-frequency kernels, which …
