摘要(中) 電力線通訊主要是透過電力線載波的方式進行資料傳輸,所以可利用
現有的電力線路,可節省佈線上的花費。
在本篇論文中,設計並且以Digital signal processing(dsp)實現了在電
力線上通訊的軟體定義OFDM發射機與接收機。此平台由C6416 DSP Starter
Kit(DSK)搭配FPGA 板、以及電力線類比前級組合而成。在發射機之訊
號處理模組中設計高速迴旋碼編碼、訊號交錯、星座圖映射、反快速傅立
葉轉換、循環字首置入和前導符碼置入等,而在接收機設計了訊號同步
器、快速傅立葉轉換、通道估測、通道等化、硬式決策、訊號解交錯及通
道解碼等。傳送之訊號頻段範圍1.91MHz 16.66MHz。摘要(英) 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.關鍵字(中) ★ 電力線通訊
