5. Fuzzy Based power control system Using ANFIS and MIMO-OFDM Techniques in Cognitive Radio Networks
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : Cognitive Radio technology is used for efficient utilization of the spectrum. There are two types of users, one is the Primary user (PU), and the second one is the Secondary user (SU). In those users, PU is having the license to use the spectrum. The SU does not have the license to use the spectrum. READ MORE
