摘要：The statistical properties of the noise in shallow water channels was investigated. It was found that the noise was non-Gaussian distributed and companied by considerable impulsiveness. Alpha-stable distribution was introduced as a statistical model to the noise. A robust decision-feedback equalizer (DFE) using constant modulus (CM) criterion based on fractional lower-order statistics (FLOS) theory was presented to recover transmitted signals in such shallow water channels. Data analysis results demonstrate the good performance of this algorithm.
