Abstract :
Direct conversion from RF to baseband transforms received RF signals into its digital equivalent immediately after an antennae. Followed digital signal processing using the dynamically downloadable software according to a specific standard corresponding to the received signal type makes these systems incredibly flexible in terms of frequency bands and protocols used. However the broadband receivers in such systems have to be protected from strong interfering signals that can be picked up within the broad receiver bandwidth that is significantly larger than spectrum width of any signals of interest. Since interference is not predictable its cancelling has to be done by adaptive means. How it may be done and what results we may obtain is the main topic of that paper.
