Abstract:
1. A digital transceiver for multicarrier modulation communications, comprising: pre-modulation circuitry for performing pre-modulation processing of digital data; digital signal processing circuitry for performing multicarrier modulation of digital data processed by the pre-modulation circuitry; configurable port subsystem for subdividing one or more high-data-rate and high-signaling-bandwidth ports into multiple lower-data-rate and lower-signaling-bandwidth ports; interface circuitry, for communicating modulated data from the digital signal processing circuitry to one or more of the subdivided ports; data memory, coupled to the digital signal processing circuitry, for storing modulated data corresponding to the selected number of ports, wherein the selected number of ports is selected from a set of port configurations including configuration circuitry, for coupling the pre-modulation circuitry, digital signal processing circuitry, and the interface circuitry, to process transmission data for a selected number of the subdivided ports.
