Abstract

The use of a 1-step least mean square (LMS) linear predictor for sinusoidal phase and amplitude jitter cancellation is considered in the paper. The structure of the algorithm is very simple; it is very attractive for real time signal processing and hardware implementation. The use of ellipse eccentricity epsiv as a figure of merit (FOM) for the degree of cancellation is discussed in the paper. A phenomenon of amplitude modulation to phase modulation (AM-to-PM) conversion is characterized and analyzed. The performance of the algorithm over an additive white Gaussian noise channel is studied by simulations.
