| dc.description.abstract | 將多輸入多輸出(Multiple Input Multiple Output, MIMO)與正交分頻多工技術(Orthogonal frequency division multiplexing, OFDM)結合已被視為下一代無線區域網路技術，此篇論文根據IEEE 802.11n WWise聯盟所提出之草案建構兩根傳送天線及兩根接收天線的MIMO-OFDM系統基頻接收機，整合了封包偵測、符元時序同步、取樣時間偏差更正、載波頻率偏移更正、通道估計，並對載波頻率偏移更正及通道估計部分特別提出新演算法及特殊情況討論，最後，以VHDL語言設計基頻收發機系統，並完成FPGA驗證。 | zh_TW |
| dc.description.abstract | The combination of multiple-input multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) is regarded as the next-generation wireless LAN technology. In this paper, we propose a MIMO-OFDM baseband transceiver with two transmit antennas and two receive antennas based on the WWiSE proposal. We devise a solution that integrates frame detection, symbol timing synchronization, sample timing offset synchronization, carrier frequency offset correction, and channel estimation for MIMO-OFDM transmission. With Focus on the part of carrier frequency offset correction, and channel estimation, a new algorithm is proposed in this thesis. Finally, the baseband transceiver is modeled by VHDL and designed with FPGA implementation. | en_US |
