Abstract. The theory of mobile communications aims at the study of point-to-point connections, perturbed by thermal noise (Gaussian), unfavorable propagation conditions, as well as channel variations. Given that a system (or a radio connection) does not have exclusive ownership over the allocated frequency band, all other radio emitters, be they nearer or father away, will constantly produce interferences, which, in turn, will limit the performance of the system. In the following, we will analyze the basic elements of multi-user communication.
