Implementation of Transmitter’s Physical Layer on Low-voltage Power Line broadband Carrier Communication System
In this paper, implementation technique of transmitter’s physicial layer on low-voltage power line broadband carrier communication system is studied. The transmitter’s physical layer include channel coding module, OFDM modulator, constellation mapper, iFFT module, cyclic prefix and window module, orthogonal modulation module and inseting preamble module. Turbo interleaver, encoding module and iFFT module’ FPGA implementing methods are introduced and analysed in details. Its results have practical value for the related research and development projects.
