Abstract

A smart algorithm for the decomposition of a channel into its subchannels in the discrete multitone communications is proposed in this paper. This algorithm evaluates the unevenness and energy distribution of the channel spectrum in order to get a variable adaptive partitioning of the channel. It is shown that the proposed algorithm leads to a near optimum performance of the discrete multitone transceiver. This flexible and smart splitting of the channel suffers less from the aliasing problem that exists in blind decompositions using fixed transforms. This paper extends the fixed discrete multitone to the flexible unequal bandwidth multi-channel concept which has significant potentials for performance improvements in high-speed digital communications.
