RESUMO

In this work an algorithm for the solution of an integral equation, which can efficiently be applied to estimate the coverage areaof a cellular system, has been developed. This algorithm is compared with the original proposed algorithm and also woth Ray tracing Techiniques for the same applications. The Ray Tracing Tecniques uses the image Tecnique to trace thirty different classes of rays, which are characterised by multiplicity of the paths and also the nature of graund. The coefficients of reflection and diffraction have been calculeted by using the classical Fresnel and the Uniform Theory of Diffraction equations respectively, and have been modified to include the roufhness of the ground. Both algorithms have been used to calculate the fiels intensity along a land profile and also a mountainous region South comparison takes into consideration the quality of the results as well as the processing time of both algorithms.
