Noise reduction for digital communications – A modified Costas loop [PDF]
, 2020 An efficient way of noise reduction has been presented: A modified Costas loop called as Masterpiece. The basic version of the Costas loop has been developed for SSB SC demodulation, but the same circuit can be applied for QAM demodulation as well. Noise

Vojnotehnički Glasnik, 2015 In GPS receivers, navigation bit allocation is performed throughout the process of signal tracking and detection. In the process of signal tracking, the locally generated signal must be synchronized with the received signal. The Costas phase-locked loop (

The Phase-Locked Loop and Costas Loop
International Journal of Contemporary Research and Review, 2017 In this study, the classical phase-locked loop (PLL) and Costas loop are investigated together. How the synchronization is obtained by the carrier recovery from the sinusoidal reference signal is mathematically shown with some assumptions and presented. It is concluded from this paper that Costas loop produces about half of the error signal produced by
