| dc.description.abstract | 長期演進技術(Long Term Evolution, LTE)為第四代行動通訊重要技術之一，此技術之上行鏈路為單載波頻分多址(Single-Carrier Frequency Division Multiple Access, SC-FDMA)系統，基本架構相同於(Orthogonal Frequency Division Multiplexing, OFDM)，SC-FDMA 是OFDM 先經由預編碼運算，此運算是經由離散傅立葉轉換(Discrete Fourier Transform, DFT)完成，使用預前編碼可降低均峰比(Peak-to-Average Power Ratio, PAPR)，有效降低功率使用而降低製造成本。
此篇論文將利用可程式化邏輯閘陣列(Field-Programmable Gate Array, FPGA)板實現，實現符合LTE 上行鏈路規格之發射機與接收機。在發射機之訊號處理模組中設計了串列轉並列處理器、星座圖映射器、DFT 處理器、IFFT 處理器、循環字首置入器和領航碼置入器等，而在接收機設計了訊號同步器、FFT 處理器、通道估測器、通道等化器、IDFT 處理器等。 | zh_TW |
| dc.description.abstract | LTE (Long Term Evolution) is important for fourth generation of mobile communication technologies. On the uplink transmission, the LTE system uses SC-FDMA (Single-Carrier Frequency Division Multiple Access) technology, is a technique essentially the same structure as OFDMA (Orthogonal Frequency Division Multiple Access). SC-FDMA pre-codes its information-bearing symbols by DFT (Discrete Fourier Transform). This pre-coding operation can reduce PAPR and can benefit power efficiency and reduce manufacturing cost.
In this thesis, we conduct design and implementation of LTE uplink transceiver with FPGA (Field-programmable Gate Array). The transmitter includes parallel-to-serial module, constellation mapper, DFT, Invers FFT, cyclic prefix inserter and pilot inserter. The receiver includes signal synchronizer, FFT, channel estimator, channel equalizer, Invers DFT etc. | en_US |
