Radio frequency interference suppression in DSL

This chapter focuses on techniques for suppressing radio-frequency interference (RFI) in DSL. Amateur radio and AM radio are identified as the main RFI sources capable of severely degrading DSL performance. The chapter describes effective methods for suppressing RFI in both the analog and the digital part of the DSL modem, evaluates their performance, compares their complexity, and gives advice on the selection of canceller parameters. 13.
