CR is envisioned as the most promising wireless technology for optimizing the usage of radio frequency spectrum and for insuring reliable communication. A multi-user Cognitive Radio (CR) network resolves the problem of spectrum underutilization and enables the deployment of new wireless applications in the fast growing wireless communication area. Hence a multi-user CR network using scalar wavelets is considered in this paper for evaluating the performance characteristics. Both mathematical and experimental analysis of the proposed system is given in detail. Spectrum efficiency, sidelobe suppression, error performance and complexity analysis of the system are analyzed.
