摘要： A transform circuit includes a first circuit and a second circuit. The first circuit and the second circuit implement first and second mappings that together generate a pre-defined transform of N digital data symbols. The first circuit maps a set of N digital data symbols from N parallel data streams to N analog data symbols by generating N sets of first weighted sums of the N digital data symbols. Each respective first weighted sum is defined by a respective set of pre-determined first weighting values in a first matrix. The second circuit maps the N analog data symbols to a sequence of N output signals over N time intervals. Each of the N output signals corresponds to a respective second weighted sum of the N analog data symbols. Each respective second weighted sum is defined by a respective set of pre-determined second weighting values in a second matrix.

摘要： A communication system utilizing an adjustable link has at least a first data transmission circuit including at least a first communication link circuit. The first communication link circuit has a baseband circuit and at least a passband circuit. The baseband circuit corresponds to a baseband sub-channel and the passband circuit corresponds to a passband sub-channel. The first communication link circuit also includes a circuit that distributes a first subset of a data stream having a first symbol rate to the baseband circuit and a second subset of the data stream having a second symbol rate to the passband circuit. The baseband sub-channel and the passband sub-channel are separated by an adjacent guardband of frequencies. The passband carrier frequency is adjusted to define the guardband and the guardband corresponds to a first notch in a channel response of a first communications channel.

摘要： A multi-tone system includes a data transmission circuit with an interface for receiving a data stream for transmission, a data steam splitter that splits the data stream to produce multiple substreams and a plurality of parallel data preparation circuits. Each data preparation circuit prepares a respective substream for transmission and generates a respective sub-channel signal. At least a first data preparation circuit of the plurality of parallel data preparation circuits includes a first analog filter for filtering a first substream. The first analog filter operates at a sample rate greater than the respective symbol rate of the first substream. The first analog filter provides pre-emphasis of the respective sub-channel signal and attenuation of signals outside of a respective band of frequencies corresponding to the respective sub-channel signal. The data transmission circuit also includes a combiner for combining respective sub-channel signals to generate a data transmission signal.
