Costas Loop for BPSK Using Phasor Rotator Circuit
2017A Costas loop for BPSK is described that has another topology than the types described in Chaps. 3 and 5. The circuit considered here does not use a VCO (voltage-controlled oscillator) or DCO (digital-controlled oscillator) for frequency and phase tracking; the local oscillator is simply an ordinary fixed frequency oscillator.

Costas Loop for Quadrature Amplitude Modulation
2017A Costas loop for the reception of Quadrature Amplitude Modulation (QAM) signals is presented in this chapter. The generation of the QAM signal is described first. When the data signals (I and Q in this case) are unfiltered, the modulated QAM signal would occupy a large frequency range. To reduce bandwidth, the I and Q signals are usually filtered.

Non-linear analysis of a modified QPSK Costas loop
IFAC-PapersOnLine, 2019 A Costas loop is one of the classical phase-locked loop based circuits, which demodulates data and recovers carrier from the input signal. The Costas loop is essentially a nonlinear control system and its nonlinear analysis is a challenging task. In this

Nonlinear Models of BPSK Costas Loop
Proceedings of the 11th International Conference on Informatics in Control, Automation and Robotics, 2014Rigorous nonlinear analysis of the physical model of Costas loop is very difficult task, so for analysis, simplified mathematical models and numerical 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 ...
