Patent ID: 8115605

Claim:
A power line communications (“PLC”) device having at least one of communications data transmission and reception capabilities comprises a physical communications protocol layer module adapted for operating in accordance with a plurality of communications signal transmission operating modes, wherein the physical layer module includes: a module for performing Fourier transform operations, wherein the Fourier module is dynamically configurable to select different data processing operations in accordance with a selected communications signal transmission operating mode; a selection module coupled to the Fourier transform module, wherein: the selection module provides for selection between different communications signal transmission operating modes for the PLC device from the plurality of communications signal transmission modes, each of the communications signal transmission modes corresponds to a different transmission data structure defined in accordance with power line network operating characteristics and communication protocol requirements, and the communications signal transmission modes comprise a wavelet filtered band OFDM mode and a non-wavelet filtered band OFDM mode; and a module for converting between parallel and serial symbol data coupled to the selection module, wherein the symbol data converting module processes a transmission data block for the power line network based on the operating mode selected by the selection module.
