Abstract
Strong narrowband signals interfering with the reception of a desired broadband signal in systems such as spread spectrum systems are continuously suppressed by converting the received signal to a frequency-domain representation thereof wherein strong narrowband interference components appear as strong impulse components. These impulsive components are blanked or clipped at a level that is a function of the average magnitude of the input signal. Resulting suppressed frequency-domain signals are reconverted to time-domain signals that are then available for further processing by conventional broadband signal receivers.
