With the advent of high-performance processors appears the ability of using composite waveforms as carrying oscillations and complex modulation methods with modulating signals that might not meet narrow-band conditions. These signals couldn-t be received using common methods based on correlation processing and matched filtering. It is offered to represent carrying oscillations and modulating signals using state space model. Synthesis of optimal algorithm of receiving of signals that don-t meet narrow-band conditions in general case and are represented using state space model is performed. The algorithm includes solution of Kalman filter equation for different hypotheses. It is shown Kalman algorithm for given model can be represented as recirculator with transforma.
