Power Line Communications (PLC) has attracted much attention due to the wide availability of power distribution lines. PLC can transmit signal over the existing AC electrical wiring without building whole new network. In this thesis,we design and implement a software dened OFDM transceiver over powerline on the dsp development platform. In this platform, we use C6416 DSP Starter Kit (dsk)、FPGA and PLC Analogy-Front-End (AFE). The transmitter includes high-rate convolutional encoder, signal interleaver, constellation mapper,Invers FFT, cyclic prex inserter and preamble inserter. The receiver includes signal synchronizer, FFT, channel estimator, channel equalizer, hard decider, signal de-interleaver and channel decoder etc. Transmission bandwidth between 1:91MHz and 16:66MHz.
