Performance Analysis and Optimization of $\hbox{T}_{\rm c}$-DTR IR-UWB Receivers Over Multipath Fading Channels With Tone Interference
2011
IEEE Transactions on Vehicular Technology
Preserved Fulltext
In this paper, we analyze the performance of a particular class of Transmitted-Reference (TR) receivers for Impulse Radio (IR-) Ultra Wide Band (UWB) communication systems, which is called Chip-Time Differential ...
It is shown that the Tc-DTR scheme provides more degrees of freedom for performance optimization, and it is inherently more robust to NBI than other non-coherent receivers. ...
Channel Model We consider a frequency-selective multipath fading propagation channel further impaired by NBI. ...

Specifically, we derive the uncoded bit error probability (BEP) of different TR signaling schemes, including TR and differential TR (DTR) signaling valid for a broad class of fading channels. ...
We quantify the effects of NBI and channel power dispersion profile on the optimum integration interval of an AcR. Finally, we compare TR and DTR signaling in terms of their sensitivity to NBI. ...

In the simulation the various effects of propagation (path loss, lognormal shadowing and multipath fading) and Additive White Gaussian Noise (AWGN) are considered; the receivers used are of Rake type. ...
In the framework of the present thesis, the appropriateness of IR-UWB as PHY in M2M indoor networks is evaluated. ...
Για την περίπτωση των σημάτων UWB, θεωρώντας ότι το σύνολο των κόμβων βρίσκεται σε εσωτερικό χώρο (περιβάλλον indoor), χρησιμοποιήθηκε το μοντέλο πολυδιαδρομικής λήψης (multipath channel model) που προτάθηκε ...

Wireless channels are often multipath channels. In a multipath channel, a path can be defined as a copy of the transmitted signal arriving at the receiver with a particular delay and amplitude. ...
GD-RAKE is obtained by the combination of two advanced RAKE receivers: the decorrelating discrete time RAKE receiver (D-DTR) and the generalized RAKE receiver (G-RAKE). ...
To e lim in a te the need for com plex acquisition and tra ckin g devices and to avoid th e ir drawbacks, the conventional discrete-tim e R A K E receiver (C -D T R ) has been proposed in [7] . ...
