The behavior of a Costas loop in the presence of space telemetry signals
IEEE Transactions on Communications, 1992When the Costas loop is operated in the presence of a residual carrier space telemetry signal, the loop reconstructs its carrier reference from an input signal whose carrier component is not completely suppressed. The telemetry signal investigated in this work is generated by phase shift-keying the data onto a subcarrier and then phase modulating onto ...

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.

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.
