Abstract :
Heterodyne filters provide both tunable and adaptive filters with applications in narrow-band interference attenuation for spread-spectrum and other broadband communications systems. A new complex-arithmetic version of the tunable heterodyne filter offers significant hardware savings over previous versions and can more easily be implemented in adaptive filter applications.
