In this talk we will examine various digital communication blocks used in broadband applications. The focus of the talk will be on the Digital Subscriber Lines (xDSL) for high-speed connections over the existing twisted pair copper lines. These new technologies allow very high-speed data transfer ranging from several KHz for HDSL to 10 MHz for ADSL and over 50 MHz for VDSL systems. The talk will cover various modulation, line-coding, equalization, and echo cancelation methods used for xDSL.
