No license is required for this low power- range limited transmitter designed according to FCC regulation. Frequency modulation has several advantages over the system of amplitude modulation (AM). The most important is that an FM has greater freedom from interference and static. Various electrical disturbances such as those caused by thunderstorms and car ignition

AI FOR COGNINITIVE RADIO Abstract: Cognitive radio (CR) is an enabling technology for numerous new capabilities such as spectrum access‚ spectrum sensing‚ spectrum decision‚ spectrum sharing and self organizing networks. This paper reviews several AI techniques used in cognitive radios such as : artificial neural network (ANN)‚ hidden Markov models (HMMs)‚ metahueristic algorithms‚ these techniques are proposed to provide the cognition capability in a cognitive engine. The modern

Monoalphabetic substitution ciphers used only a single replacement scheme — sometimes termed an "alphabet"; this could be easily broken‚ for example‚ by using frequency analysis. Somewhat more secure were schemes involving multiple alphabets‚ polyalphabetic ciphers. Because such schemes were implemented by hand‚ only a handful of different alphabets could be used; anything more complex would be impractical. However
