Abstract

This paper presents a study on existing techniques on cancellation of strong interference in frequency bands adjacent to the radio receivers. It also proposed a new configuration for cancellation of this strong interference, merging techniques known with a new model developed. The idea is to build an end cancellation/attenuation interference of affordable sub-system, that is universal and adjustable to the technology of radio frequency used by the receiver (compensating the intermodulation distortion created in LNA).
