In a wireless communication system, especially in the field of transport, the possibility of multi-useris present in the same frequency band. To ensure best quality of information exchange and a high data rate, it necessary to establish an efficient communication management algorithm.
This paper presents an original multiple access technique that provides good performances for several and various users simultaneously. A model based on the principle of Cognitive Radio that is able to detect the modulation typewith the presence of noise is also described.
