Systems and methods for reducing latency through motion estimation and compensation techniques are disclosed.

A method for transmitting and receiving a radio frequency (RF) signal over an optical channel is described, where a nonlinear optical harmonic generation device is used to increase the system performance. The RF signal is phase modulated onto an optical carrier. The received optical carrier propagates through a nonlinear optical harmonic generation device, which increases a phase modulation depth at the harmonic wavelength.

By photo-detecting both the fundamental and the harmonic optical wavelengths, then properly scaling and subtracting the two photo-detected signals, the enhanced modulation depth at the harmonic optical wavelength can be used to cancel out unwanted nonlinear distortions thereby linearizing the measured RF signal. The method uses a phase-to-amplitude conversion device to change phase modulation into amplitude modulation, and is compatible with phase-to-amplitude devices that perform photonic down-conversion thereby allowing for reduced bandwidth photo-detectors. |
