Two-dimensional impulse noise model for digitalsubscriber loopenvironment

The wideband impulse noise modelling over the subscriber loop recently conducted over the German telephone network is extended to the narrowband scenario. The narrowband impulse noise is resolved into in-phase and quadrature components and each component modelled as a generalised error distribution. Simulation is used to verify the theory.

Performance of microcellular mobile radio in a cochannel interference, natural, and man-made noise environment

A model is developed for performance analysis of a microcellular digital mobile radio system with Rayleigh-faded cochannel interference, Gaussian noise, and narrowband impulsive noise (Middleton's Class A noise) using the differential phase shift keying (DPSK) modulation technique. The desired signal is assumed to be Rician faded. The effects of selection diversity on the performance are investigated and compared to the nondiversity case. The performance is measured in terms of bit error probability and spectrum efficiency. The influence of reuse distance (i.e. cluster size), traffic intensity (i.e. blocking probability), impulsive index, Rician parameter, and turning point of the dual path loss law characteristic of microcells on the performance parameters is investigated in detail.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
