Time-frequency based analysis of wireless signals

This paper deals with signal characterization in communication systems. An algorithm for components separation of highly multicomponent wireless signals has been described. Eigenvalue decomposition method along with time-frequency signal distribution is used. Approach has been tested on synthetic IEEE 802.11b wireless signal. This method can be useful for the elimination of frequency collisions - interferences that occur in wireless network systems, as well as in separation of different types of signals operating in the same frequency band.
