Standalone canceller of narrow band interference for spread spectrum receivers

A spread spectrum interference canceller includes a downconverter for amplifying and translating the received signal from the radio frequency band to baseband, said signal comprising multiple direct sequence-spread spectrum signals and multiple narrowband interferers; a digital adaptive transversal filter for processing the downconverter output signal to suppress the narrowband interferers, and for regulating the amplitude of the resulting signal; an upconverter for translating the filter output from baseband to the radio frequency band, so that the resulting interference canceller output can be processed by a spread spectrum receiver.
