ng newly developed mathematical models. Step-by-step design procedures and Simulink models are included for every type of Costas loop. These models enable designers to test circuits prior to building breadboards or prototypes, accelerating the design process considerably..978-3-319-89130-9978-3-319-72008-1

Book 2018 discusses all three variants of the Costas loop and describes their dynamic behavior, using newly developed mathematical models. Step-by-step design procedures and Simulink models are included for every type of Costas loop. These models enable designers to test circuits prior to building breadboar

Introduction: From Phase-Locked Loop to Costas Loop,t used for the synchronous reception of amplitude modulated radio signals with carrier (c). If the modulation index is less than 100%, the modulated signal is always in phase with the carrier signal (c), irrespective of the polarity of the modulating signal. The PLL then reconstructs a local carrier

Conventional Costas Loop for BPSK, Dynamic Analysis, Design Procedure, and Simulation,. Dynamic behavior of the loop is described using a novel mathematical model developed by the author. This new model allows the designer of a Costas loop to explicitly compute important key parameters (lock range, lock time, pull-in range, pull-in time) as a function of block parameters such as corn

Modified Costas Loop for QPSK,th the so-called pre-envelope signal. This is a complex signal, also referred to as “analytical signal.” The real input signal of this Costas loop is converted to the pre-envelope signal using a Hilbert transformer. The local oscillator also generates a complex output signal. It is shown that the ph

Costas Loop for m-ary Phase Shift Keying (mPSK),es, 0 or 180°. One bit can be transmitted within one symbol interval. With QPSK, the phase can take four states, 45°, 135°, 225°, or 315°; hence, 2 bits can be transmitted in one symbol interval. In m-ary PSK, however, the number of phase states is made larger than 4, e.g., m = 8. For m = 8, the pha
