Nowadays simplified mathematical models and numerical simulation are widely used for the analysis of QPSK Costas loop. In the work it is shown that the use of simplified mathematical models and the application of non-rigorous methods of analysis may lead to wrong conclusions concerning the operability of real model of QPSK Costas loop.
A modification of BPSK Costas loop, where low pass filters are applied separately from the loop, is considered. Such modification of the loop can work with non-sinusoidal signals or with some special phase detectors instead of multipliers. In this paper a general approach to the analytical computation of phase detector characteristic of the loop for general periodic signal waveforms is demonstrated...
Nonlinear analysis of BPSK Costas loop is a difficult task, so for its analysis simplified mathematical models and their simulation are widely used. In the work it is shown that the use of simplified mathematical models and the application of non-rigorous methods of analysis may lead to wrong conclusions concerning the operability of real model of BPSK Costas loop. Corresponding examples of BPSK Costas...
