Abstract
A simple algorithm for detection of timing error of a synchronous, band-limited, BPSK or QPSK data stream is proposed. The algorithm requires only two samples per symbol for its operation. One of the two samples is also used for the symbol decision. Derivation of the s curve reveals a sinusoidal shape.

High-order phase tracking loop with segmented proportional and integral controls

TL;DR: In this paper, a phase detector is employed to obtain phase differences between a copy of the output signal and a second reference clock signal, and the phase differences are employed in an integral phase control loop within the feedback loop to lock the phase locked loop device to the center frequency of the second reference signal.

Costas Loop for Quadrature Amplitude Modulation

Roland Best
TL;DR: A Costas loop for the reception of Quadrature Amplitude Modulation (QAM) signals is presented and it is shown that so-called Nyquist filters are the best choice, because they allow the receiver to detect the signal without Inter Symbol Interference (ISI).
