In Ultra Wideband (UWB) systems information is carried in very short pulses, covering extremely wide spectrum bandwidth. Waveform of these elementary pulses, called monocycles, essentially impacts the performance of complete system. In this paper we describe one novel class of monocycles, called coded monocycles, which is based on employing direct-sequence spread spectrum technique. Application of...
This paper studies the outage probability of a dual-hop amplify-and-forward (AF) relay systems where the source-relay and the relay-destination channels experience Rayleigh and k-μ fading, respectively. The relay node is corrupted by Rayleigh faded multiple co-channel interferences. New infinite series expression for outage probability of the end-to-end signal-to-interference and noise ratio (SINR)...
In this paper, simulations of downlink Long Term Evolution (LTE) system network capacities were performed. The existing WCDMA network is used as reference for LTE radio network design: locations, antenna directions / types / tilts / heights. Simulation is performed for uniform and non-uniform network traffic distribution as well as for case with inter-cell interference coordination.
