In the article, using subsequent transformations of the structure and mathematical model of a classic gradient jammer canceller, the mathematical model and the structure of a gradient jammer canceller with a pre-processor are obtained. A new structure provides that the adaptation speed of a canceller does not depend on the spread of the eigenvalues of the input signal correlation matrix. An intermediate model provides the analysis of weight misadjustment of the classic gradient jammer canceller. The aim of the new mathematical model is a subsequent analysis of weight misadjustment of the jammer canceller with a stable adaptation speed.
