A multi-user Cognitive Radio (CR) network resolves the problem of spectrum under-utilization and enables the deployment of new wireless applications in the fast growing wireless communication area. The unique feature of CR is its ability to use the vacant band while insuring minimum interference to adjacent users. So, modulation and multiple access schemes insuring minimum interference are required for CR transmission. Multi-wavelets are rarely considered in the field of wireless communication. They are orthogonal and symmetric waveforms with short support and can insure lower multiple access interference in a multi-user environment.
