摘要

The ongoing developments in the field of high-speed data transmission over twisted-pair cables (DSL- Digital Subscriber Line) leads to methods that can exploit the transmission media with increased Efficiency. MIMO (Multiple-Input Multiple-Output) transmission, i.e., the coordinated use of many pairs Within a bundle, is such an emerging DSL technology. A further goal is to maintain a certain transmission Quality in the presence of non-DSL noise. For example, cancellation techniques to combat narrowband Radio interference, which is generated by radio amateur transmitters and may be picked up by the wire Close to the subscriber or by the in-house wiring, become important.
