- Abstract
We consider the fast digital algorithm for the phase locking of the coherent demodulators of the binary phase-shift keyed signals, the one similar to the well-established Costas circuit. Unlike the common counterparts, the specified algorithm can be practically implemented with the minimum number of simple arithmetic operations and it is fully compatible with the modern hardware components available. We obtain the set of nonlinear equations describing the process of phase locking and allowing us to determine the properties of the introduced digital locking algorithm analytically. By simulations, the interference immunity of the algorithm for the phase locking is demonstrated, and its operability corroborated. The possibility of its hardware implementation on the basis of the modern programmable logic devices is shown.
