| dc.description.abstract | 低軌道通訊的技術蓬勃發展下，數位衛星廣播系統成不可或缺的關鍵。衛星在高
速移動的情況下與地面站所產生之都普勒頻率偏移成為重要的課題，也因應高通量資料
率串流的通訊技術，DVB-S2 相較於前一代有更好的傳輸量，支援 8PSK、16APSK、
32APSK，使得在不同訊雜比(SNR)下能選擇更有效益的調變與碼率。
本論文針對 DVB-S2 接收端之載波頻率同步與訊框同步的硬體架構設計與實現，
探討其性能。載波頻率同步使用差分頻率估測器(Differential Frequency Estimator)、導向
決策器(Decision-Directed)與迴路濾波器(Loop Filter)計算與修正頻率偏移，訊框同步包
含 MODCOD 偵測器(MODCOD Detector)、抓取訊號及相位修正、訊框彈性器(Frame
Elasticizer)與實體層解攪亂器(PL Descrambler)。 | zh_TW |
| dc.description.abstract | With the flourishing development of Low Earth Orbit (LEO) communications technology,
digital video broadcasting systems for satellite (DVB-S) have become indispensable. The
Doppler effect generated when satellites are in rapid motion relative to ground stations has
become a crucial issue. In response to high-throughput data rate streaming communication
technology, DVB-S2 offers improved throughput compared to the previous generation. It
supports 8PSK, 16APSK, and 32APSK, allowing for the selection of more efficient modulation
and coding schemes under different signal-to-noise ratios (SNR).
In this thesis, it focuses on the hardware architecture design and implementation of carrier
frequency synchronization and frame synchronization for DVB-S2 receivers, along with a
performance evaluation. Carrier frequency synchronization includes a Differential Frequency
Estimator, Decision-Directed Phase Estimator, and Loop Filter to compute and correct
frequency offsets. Frame synchronization includes MODCOD Detector, signal catcher and
phase correction, Frame Elasticizer, and Physical Layer Descrambler. | en_US |
