Applications range from antijam systems, to code-division multiple access systems, to system designed to combat multipath. It is the intention of this thesis to provide a tutorial treatment of the theory of spread-spectrum communications including a computer aided analysis on Direct-Sequence and Frequency-Hopping systems. Results of the jamming rejection algorithms for estimating and suppressing narrowband interference in DS and FH systems are presented. Techniques for determining the coefficients of a linear interference suppression filter (which are based on linear prediction and conventional spectral analysis methods), are described.30 cm.Spread spectrum communications.Digital communications.ix, 129 leaves;
