Abstract:	WiGig規範為新一代無線寬頻網路標準，以現行的IEEE802.11 標準為基礎，擬訂實體層 ( PHY ) 與媒介擷取控制層 ( MAC ) 的技術與工程規格，其系統操作廣泛的應用在60 GHz之上。本論文主要研究WIGIG網路架構，針對WIGIG 規範所訂定的通道編碼與調變，在低密度奇偶校驗 ( LDPC ) 碼與迴旋 ( Convolutional ) 碼參數配置以及不同的調變技術下，作系統效能分析，並且運用通道估測技術與等化器來解決多路徑衰減所產生的效應。然後，在不改變整體碼率的情況下，我們利用不同大小的低密度奇偶校驗碼與交叉存取的應用，搭配不同的調變，分析系統效能，以及比較各種參數及編碼方式，取得最佳效能組合。由於無線寬頻網路擁有眾多的優越性，為了使其能夠早日普遍化，於是我們希望藉由系統模型的建立與分析，了解整個WiGig系統架構，以便日後實際建構系統設備時有參考依據。WiGig is a new generation wireless broadband network standard. This standard mainly targets technology and specification in IEEE 802.11 Networks, including the physical layer and medium access control layer, of fixed point-to-multipoint broadband wireless access systems providing multiple services. It is broadly applicable to systems operating at 60 GHz. This dissertation mainly is to study the system infrastructure of WiGig Networks.We especially focus on the channel coding and modulation in the specification of to analyze the performance of system under different LDPC coding and Convolution coding parameters set as well as different modulation techniques. We also study the channel estimation technique and equalizer to resolve the effect of multipath fading. Then, we use different sizes of LDPC coding as well as interleaving without changing overall coding rate to find the best system performance of modulation. As expected, the wireless broadband network will be employed in the new future. This thesis has successfully provided the necessary analysis and model for implementing the network.
