In adaptive phased-array radar the cancellation of directional interference is limited by a number of mismatching sources; the main one is the frequency-dependent amplitude and phase mismatches between the radar receiving channels. A digital equalisation filter is needed to compensate for these mismatches. In this survey paper we describe the theory and practice of digital equaliser. We also demonstrate...
The paper analyzes the convergence of the sign algorithm when the noise distribution has a dead zone that includes the origin. The analysis is done in the context of the identification of a plant with a stationary Gaussian input. Upper bounds of the time-averaged mean absolute excess estimation error and the time-averaged mean norm of the weight misalignment vector are derived. The former bound does...
