topology-optimization

This paper deals with the modeling of the statistical distribution of the effective gain of terminals. This incorporates both the characteristics of the antenna’s radiation pattern in the situation of use, and the characteristics of the local propagation environment. A frequency-wise and frequency-correlated log-normally-distributed effective-gain model is proposed as a standard model of wide – although not universal – validity. This is done mainly for the sake of simplicity and ease of use. This model is tested in a few exemplary cases of measured and simulated terminals, using a subset of the WINNER channel model for the local propagation.
