dc.description.abstract	地面數位電視廣播（DVB-T），為台灣地區所使用的數位電視廣播規格。其所採用的通訊技術為正交分頻多工（OFDM），正交分頻多工是一種多載波的調變方式，將資料分散到各個不同的頻率且互相正交的次載波。在本論文裡，針對地面數位電視廣播系統，專注於同步與通道等化器的演算法，並使用Matlab與C語言建立系統模擬平台。此平台包含數位降頻器，載波同步，時序同步與頻域等化器。最後，提出縮減記憶體之整數倍頻率誤差估計之架構，此架構可以減少記憶體使用量達90%，減少存取次數達94%和減少估計時間達37%。	zh_TW
dc.description.abstract	Digital Video Broadcasting for Terrestrial (DVB-T) is the digital TV broadcasting standard in Taiwan. The adopted communication technical is Orthogonal Frequency Division Multiplexing (OFDM). OFDM is a kind of multi-carrier modulation and divides the data into several differential and orthogonal sub-carriers. In this thesis, we focus on synchronization and channel estimation of DVB-T and build a simulation platform using Matlab and C language. This platform contains digital down conversion, carrier frequency synchronization, timing synchronization and frequency domain channel estimation. Finally, we propose a memory reduction architecture for integer carrier frequency offset estimation. This architecture reduces the usage of memory by 90 %, the memory access number is reduced by 94% and the estimation time is reduced by 37%.	en_US
