A Costas loop is a phase-locked loop (PLL) based circuit which is used for carrier frequency recovery from suppressed-carrier modulation signals (e.g....

well as demodulation, can be accomplished using a Costas loop of the appropriate order. A Costas loop is a cousin of the PLL that uses coherent quadrature...
