dc.description.abstract電力線通訊近來蓬勃發展,可藉由既有之電力線路傳遞訊號,不需重 新佈線,可解決通訊傳輸中最後一哩的問題。在本篇論文中,對電力線通 道進行了以軟體方式的測量環境,並且針對電力線通道的特有現象進行探 討,包括了特殊雜訊以及通道變化等。 此外設計並且實現了在電力線上通訊的即時軟體定義OFDM 發射機與 接收機。在平台使用了FPGA 實驗板、數位轉類比與類比轉數位開發板以 及自製電力線類比前級。在發射機之訊號處理模組中設計了串列轉並列處 理器、高速回旋碼編碼器、訊號交錯器、星座圖映射器、反快速傅立葉轉 換器、循環字首置入器和前導符碼置入器等,而在接收機設計了訊號同步 器、快速傅立葉轉換器、通道估測器、通道等化器、硬式決策器、訊號解 交錯器及通道解碼器等。傳送頻帶為2.3MHz~20MHz,在64-QAM的模式 之下最高傳輸率為42.52Mbps 。zh_TW
dc.description.abstractPower Line Communication (PLC) system is a flourishing communication technology, which can transmit signal over the existing AC electrical wiring without building whole new network and deal with the last mile issue. In this thesis, we formed a software method to measuring PLC channel’s feature and investigated a particular phenomenon of powerline channel-special noise and channel changing. In other way, we design and implement a real-time software defined OFDM transceiver over powerline. In this platform, we use FPGA, DAC/ADC EVM board and design PLC Analogy-Front-End (AFE). The transmitter includes parallel-to-serial module, high-rate convolutional encoder, signal interleaver, constellation mapper, Invers FFT, cyclic prefix 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 2.3MHz$ and 20MHz$. In 64-QAM mode, the maximum throughput is around 42.52Mbps.en_US
