Abstract

In this paper, we present a new robust direct sequence spread-spectrum concept with integrated interference reduction capabilities to reduce mixed narrowband- and broadband-interference. It combines robustness in the presence of strong interference of unknown composition with implementation simplicity and spectral efficiency. This is achieved by combining a comparatively low processing gain direct-sequence spread-spectrum system with an efficient interference reduction technique based on a simple adaptive nonlinearity employed prior to spread-spectrum demodulation. Our reliable chip accumulation technique allows to combine spectral efficiency with interference reduction capabilities comparable to traditional military spread-spectrum systems, which typically rely on a huge processing gain that is not affordable in commercial bandwidth-limited applications.
