Abstract

This paper evaluates the effects of modulation and urban shielding for modern microcellular systems. The capacity analysis makes use of the site specific ray-tracing propagation models previously developed at the University of Bristol. For a given microcellular location a site specific building database has been used to predict the signal coverage as a result of reflection, diffraction and scattering in the focal environment. Taking into account a number of system parameters, such as modulation type, antenna pattern, SNR, C/I, and outage probability, the ray-traced propagation data has been extensively analysed to provide an accurate estimation of system capacity. Using this model the impact of higher level modulation schemes such as 16-QAM are examined for microcellular networks.
