DEVICE FOR PROCESSING BROADBAND SIGNALS Russian patent published in 2006 - IPC H04B1/10 

FIELD: radio communications, possible use in communication systems with broadband signals.

SUBSTANCE: in each quadrature channel from result of multiplication of input broadband signal and harmonic supporting signal, result of multiplication of input and supporting signals is subtracted, which result of multiplication is also delayed for value τ, where τ≫τ_cor, (τ_cor - correlation interval of broadband signal), while synchronized filtration is performed relatively to signal, received by subtracting its copy, delayed for τ, from copy of signal.

EFFECT: increased resistance to narrowband interference.
