Abstract :
This paper introduces an improved direct-sequence spread spectrum interference rejection filter using the fast transversal filter (FTF) adaptive algorithm. A constraint is imposed on the FTF update, resulting in a balance of interference rejection and signal fidelity at the filter output. The constraint is controlled by a single parameter
