本文主要目標為探討使用渦輪編碼器(turbo encoder)以及經由OFDM調變(Orthogonal frequency-division multiplexing modulation)後的訊號,附載在寬頻電力線系統上,接收端的解碼效果,是否會得到更好的錯誤更正能力。本文的環境主要假設為建物室內;由於電力線上經常會因為電器的開關和不定時的運作,而產生一些無法預期的脈衝訊號。採用脈衝雜訊通道(Impulse noise model)來模擬通道中此雜訊的特徵,便顯得至為貼切。
本文主要是使用Additive White Class A Noise(AWAN) channel來模擬寬頻電力線上的環境,這也是目前較常見的電力線雜訊模型之一;整體的架構是依據IEEE 1901 標準中的實體層部分,而本文中選用的是1901 Frame Control mode來創建。利用電腦軟體模擬較為廣泛使用的接收器,並且分析其錯誤位元率。為了降低環境中較大雜訊所造成的影響,在本文中也使用目前最常用的限幅器(Limiter)用以提高解碼的效能。
The main objective in this paper is to explore the use of turbo encoder and the signal which use OFDM(Orthogonal frequency-division multiplexing) modulation. For broadband power line communication systems, we wonder whether it will get the better error correction capacity at the front-end receiver. In this paper, the environment is assumed that in the home building ; It produces some unexpected impulse noise thanks to turn the electric equipment on and off Occasionally. Here we adopt Impulse noise model to simulate the characteristics of this channel, it’s more appropriate.
In this paper we use Additive White Class A Noise (AWAN) channel to simulate broadband power line environment, which is the more common model of power line noise model currently; the overall architecture is based on the part of the physical layer in IEEE 1901 standard, and we select the 1901 Frame Control mode to create it. By using computer software to simulate the widely used receiver, and we can analyze the bit error rate. In order to reduce the large noise in the environment, we also use the limiter to improve the decoding performance in this paper.
