We propose a novel detection method for non-coherent synchronization (signal acquisition) in multi-access UWB impulse radio (IR) networks. It is designed to solve the IUI (Inter-User Interference) that occurs in some ad-hoc networks where concurrent transm ...
Reliable positioning of cellular users in a mobile environment requires accurate resolving of overlapping multipath components. However, this task is difficult due to fast channel fading conditions and data ill-conditioning, which limit the performance of ...
Due to environmental concerns and strict constraints on interference imposed on other networks, the radiated power of emerging pervasive wireless networks needs to be strictly limited, yet without sacrificing acceptable data rates. Pulsed Time-Hopping Ultr ...
We evaluate system capacities for multicellular systems with different multiple access strategies. The interference from another cell sharing the same frequency is calculated, and the total interference arising from the frequency reuse pattern is evaluated ...
As the demand for wireless mobile communication services is constantly growing, the need for mobile systems and devices that support much higher data rates is increasing. The available bandwidth is limited and expensive, thus we need new technologies that ...

We propose a detection method for pulse level synchronization in the presence of Inter-User Interference (IUI),in particular in the Near-far scenario. Further, we investigate concurrent transmissions using the same time hopping code. ...
In this paper we determine bounds of the capacity region of a two-user multiple-access channel with Rayleigh fading when neither the transmitters nor the receiver has channel state information (CSI). We assume that the fading coefficients as well as the ad ...

The paper discusses the performance of a MIMO-extended UMTS-FDD downlink with a 2x2 and a 4x4 antenna configuration. An analytical expression for the average signal to interference ratio (SIR) of a space-time (ST) RAKE receiver in an interference dominated ...
