RASI 1994 - 1995: Microcellular propagation modelling with ray tracing (as a part of microcellular WCDMA system simulator development)

A ray tracing program coded with ANSI-C was developed. The ray tracing is done based on the ray launching method and environment modelled with planes, and it takes free space propagation, reflections, penetration and diffraction into account. The program is developed for microcellular environments. Publications [1, 2, 3, 6, 8, 9, 10] are results from this work.

MAST 1996 - 1997: Modeling of nonideal system components

The work comprised development of nonideal RF models for link performance simulations, and the outcome was a memoryless power amplifier model and a mixer/modulator/demodulator model to be used in COSSAP, Matlab or other simulation environment. Publications [4, 5, 7, 11] are originated from this work.
