A NOVEL MODEL OF DSP FOR LINE ENHANCER

An innovative adaptive line enhancer (ALE) structure is presented in this work. The adaptive filter's auto regressive-moving average (ARMA) structure is based on traditional Laguerre orthogonal func­tions. The orthogonal set's poles' frequencies and radii allow for tuning. Higher-order statistics are used to tune these terms in this contribution. Fourth-order cumulants' qualities are used to help with harmonic retrieval of the sinusoids embedded in the input signal. Since the feed-forward filter parameters are linearly connected to the filter output, further adaption of them is simple. Stability, brevity, and robustness in the presence of noise are expected benefits. Results from simulations are presented to demonstrate typical performance.
