Abstract

A new adaptive harmonic jammer canceler is proposed. It is based on the use of two sensors that enable an adaptive generation of a reference signal that is uncorrelated with the desired signal. This reference signal is used for the reconstruction of the desired signal by an adaptive subtraction method. This canceler is well suited to radio communications. A theoretical analysis of the convergence of the coupled algorithms is presented with the help of the associated ordinary differential equation introduced by L. Ljung. Numerical simulations illustrate the different proposed algorithms
