Optimierung eines Mehrtraegerverfahrens zur leitungsgebundenen Uebertragung digitaler Signale

摘要

In this contribution it is investigated, to what extent the throughput of digital signal transmission via copper cables of the local cable network can be increased compared to established techniques, especially if multicarrier systems are used, which divide the total flow of information into spectrally separated subchannels. Based on an idealized multicarrier system with very narrow and ideally band-limited subchannels, transmission parameters are individually assigned to the subsequently wider subchannels with approximately realizable band-limitation. The optimized multicarrier system provides a clear increase of throughput compared to well-established baseband and multicarrier systems.
