Fine Synchronization through UWB TH-PPM Impulse Radios
In this paper, a novel fine timing algorithm has been tested and developed to synchronize UltraWideband (UWB) signals with pulse position modulation (PPM). By applying this algorithm, we evaluate timing algorithms in both data-aided (DA) and non-data-aided (NDA) modes. Based on correlation operations, our algorithm remains operational in practical UWB settings. The proposed timing scheme consis...
متن کاملNovel Fine Synchronization Using TDT for Ultra Wideband Impulse Radios
Ultra-Wideband (UWB) technology for indoor wireless communications has received increasing consideration recently for his potential of high data rates with low-complexity transceivers. Timing synchronization represents a foremost challenge in realizing this potential. In this paper, a novel fine synchronization method has been established. By applying this method, we develop and test timing alg...
متن کاملUwb Impulse Radio with Gated Treshold Compensated Ppm Receiver
General agreement has been reached recently, that the coherent optimum receivers known from the theory of conventional communication systems are not feasible to implement low-cost and robust UltraWideBand (UWB) Impulse Radio (IR) receivers, especially if they have to offer an extremely low power consumption. Instead, Energy Detector (ED)-based noncoherent receivers have to be used [1]. Unfortun...
متن کاملFine Synchronization in UWB Ad-Hoc Environments
UWB impulse radios (UWB-IR) have attracted increasing interest due to their potential to propose high user capacity with low-complexity and low-power transceivers (Win & Sholtz, 2000). It is approved by the Federal Communications Commission’s (FCC) Report in which the UWB spectral mask is released and published in February 2002. Most of these benefits initiate from the distinctive characteristi...
متن کاملTiming Synchronization Technique for TH-PPM-Ultra Wideband Systems
This paper proposes a synchronization algorithm for time-hopping pulse position modulation ultra wideband (THPPM-UWB) systems to detect the first symbol arrival time. The transmission signals of UWB systems usually use baseband pulses with very short duration. We would present an overview of the principles of UWB impulse signals, and focus on the synchronization technique of symbol arrival time...
