Approximating the sum of log-normal random variables (RVs) is a long-standing open issue
and many studies in the old and recent literature resort to assume that the" power sum" can …

In ultra-wideband impulse radio (UWB-IR) systems, multipath-delayed received pulses may
overlap if two consecutive multipaths arrive within less than the pulse duration. This …

In this paper, the impact of timing jitter in direct sequence ultra wideband (DS-UWB) system
is investigated over multipath fading channel. Also, a novel hybrid direct sequence …

In this letter, we propose an exact analytical framework for analyzing the performance of
impulse radio (IR) ultra wide band (UWB) receiver architectures. In particular, the framework …

Multiple access analysis is presented for pulsed direct sequence (DS) and hybrid DS time
hop** (DS/TH) ultra-wideband (UWB) communications considering a Saleh-Valenzuela …

In this paper, the impact of chip duty factor (DF) on direct sequence (DS), time hop** (TH)
and hybrid DS-TH ultra wideband (UWB) systems is investigated in realistic environments …

This paper proposes fractionally spaced selective Rake (FSRake) receiver for M-ary bi-
orthogonal keying based direct sequence ultra wideband (MBOK DS-UWB) wireless …

In this paper, we present the impact of timing jitter on a direct sequence ultra wideband (DS-
UWB) system in additive white Gaussian noise (AWGN) and multipath environment. Rake …

To eliminate the requirement for a delay unit capable of processing wideband signals in a
conventional UWB transmitted reference (TR) receiver, the slightly frequency shifted (SFS) …

In this paper, two frequency domain signal processing techniques for pulse shape
modulation (PSM) ultra wideband (UWB) systems are presented. Firstly, orthogonal …
