Pattern recognition research for the TT&C signal

The diversity and flexibility of Telemetry, Tracking & Control (TT&C) systems require the receiver to be compatible with multimode signal systems, it is no doubt that this problem will be solved if the automatic recognizer can be designed. According to the characters of mixed TT&C system which includes unify S band signal system, direct sequence spread spectrum signal system and hopping frequency spread spectrum signal system, the principles of unify carrier wave extracting base on Fourier transform and spread spectrum signal detection base on delay phase multiplication are given in this paper, the recognition algorithm is also provided. The result of simulation shows that this recognition algorithm is feasible.
