Paper Abstract

Abstract: Optical Dynamic range compression (ODRC) is a new nonlinear signal processing concept that reshapes the dynamic range and signal-to-noise ratio. ODRC improves the detection sensitivity by boosting weak signals over the noise floor, while keeping the full-scale the same. Without requiring an optical receiver that has post-amplification or higher resolution, the detectable range is extended. For signals whose amplitude distribution is centered at a low value, ODRC effectively reduces the quantization error by assigning more quantization levels to weak signals, reducing the total number of bits to digitize. In amplifiers cascade, a low-noise ODRC serving as the pre-amplifier would relax the noise figure and linear range requirements of the second amplifier.
