Abstract(in English) This manuscript considers a secondary system sharing the spectrum with the primary system at the same time and same frequency. This manuscript proposes a cognitive overlay system, in which the secondary system relays the primary signal and piggybacks its own data on it. As the relay procedure, non-regenerative and regenerative repeaters are considered and performance with them are compared. The result of the analysis shows that the proposed scheme with regenerative relay allows the secondary signal to communicate at the same speed of the primary signal without any harm to it.
