Separation of Mixed Signals in Dynamic Environments: Formulation and Some Implementation

We describe algorithms and some chip implementation for separating unknown, but independent, mixture of temporal signals in static and dynamic environments. One algorithm is a modi ed HJ algorithm; the other is derived based on optimal control theory so as to maximize a functional which characterizes the linear independence of temporal signals. Moreover, we present some chip results and computer simulations and quantify the performance in static and dynamic environments.
