Abstract: Recently, Multi-Carrier Modulation (MCM) systems have become|quite popular due to many advantages. One of the most important|features of Discrete Multi-Tone (DMT) systems is rate adaptability,|and the maximum data rate for an existing loop can be easily|determined by means of adaptive loading algorithms. However,|time-variant disturbers, e.g. narrow band interference, can lead|to a significant performance loss which may be counteracted by|decreasing the data rate. Yet dynamic rate adaption is difficult|as higher protocol layers are concerned. In this paper we present|system concepts for dynamic carrier allocation and seamless rate|adaption to mitigate the introduced performance degradation. This|includes strategies for bit swapping to maintain the current data|rate as well as dynamic rate adaption. Protocols for robust and fast exchange of allocation tables between receiver and transmitter will be presented.
