FPGA-based implementation of a filter bank-based transmultiplexer for multicarrier communications

Authors propose with the real-time implementation of a transmultiplexer based on an embedded filter bank as a medium access technique for multicarrier communications, such as in broadband PLC (power-line communications). For that purpose, the signal processing algorithms have been analyzed, not only to determine the corresponding requirements, but also to optimize them for a suitable implementation. The definition of an efficient SoC-based architecture to achieve real-time performance has been carried out. The proposed architecture has been optimized in terms of datawidth, data rates and frequencies, as well as resource consumption.
