| Abstract: | Cognitive Radio is considered as a promising technique for efficient use of EM spectrum.Static management mode is adopted for military communication spectrum management(MCSM).The basic concepts and techniques of cognitive radio and the disadvantages of current MCSM are described.A new MCSM mode incorporating the concept of cognitive radio is suggested and the advantage brought by the new method is analyzed.Finally the technical difficulties faced by military EM spectrum management based on cognitive radio a... |
