A simple algorithm for detection of timing error of a synchronous, band-limited, BPSK or QPSK data stream is proposed and derivation of the s curve reveals a sinusoidal shape.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.read more

Real-time FPGA prototyping of a 15GBaud SP-16QAM coherent optical receiver with optimal interpolating for clock recovery and equalization.
TL;DR: A real-time coherent optical receiver based on a single field programmable gate array (FPGA) chip is demonstrated and the optimal interpolator significantly lowers the utilization of LUT, CARRY8, and DSP48 and can work properly under a received optical power of -40dBm.

Multiple-Symbol Parallel Interpolation in All-Digital Receiver
TL;DR: In this paper, a parallel interpolation structure for all-digital receiver makes timing adjustment for one symbol at a time, which lightens the hardware-constraint to the processing rate of the interpolator, and in turn, improves the processing speed of the receiver.
