dc.description.abstract | 本計畫為一整合型計畫之子計畫,擬為期二年,研究下世代寬頻行動通訊之傳輸訊 號處理技術,其中主要考慮多載波方式之訊號調變。一方面,我們將根據3GPP LTE 和 LTE-Advanced 標準來研究幾項重要的傳輸訊號處理功能;另方面,我們將研究更具前 瞻性的中繼傳輸技術。以上根據標準進行研究之傳輸訊號處理功能包括下行同步、通道 估計、和空時頻訊號編碼傳收,其中除了理論與演算法研究之外,並擬從事相關之數位 訊號處理器軟體實現研究。在中繼傳輸技術方面,鑒於中繼式合作通訊預期將能提升無 線通訊系統的效能,LTE-Advanced 已開始制定相關標準,但初期所考慮的傳輸技術屬 傳統技術。本計畫將研究前瞻的雙躍式中繼傳輸技術,其中主要考慮放大前送式中繼方 法。我們將考慮兩種中繼網路型態,即平行式單向中繼傳輸與三點雙向中繼傳輸,其中 前者使用多個中繼台合力形成多輸出入通訊管道,後者則以創新之實體層網路編碼提高 頻寬使用效率。 | zh_TW |
dc.description.abstract | This project is a subproject in an integrated project. It is intended for two years. In it we research into the transmission signal processing technologies for next-generation broadband mobile communication. We mainly consider the multicarrier type of signal modulation. On the one hand, we will look into several key transmission signal processing functions based on the LTE and LTE-Advanced standards; and on the other hand, we will study more forward-looking relay transmission technology. The standard-based investigation of transmission signal processing functions will consider downlink synchronization, channel estimation, and space-time-frequency coded signal transmission. Besides theoretical and algorithmic study, we will also consider digital signal processor (DSP) software implementation of the functions. In the area of relay transmission technology, we note that relay-based cooperative communication is expected to be able to enhance the performance of wireless communication systems. As a result, the LTE-Advanced body has been specifying related standards, but the transmission techniques considered initially are traditional ones. This project will study advanced two-hop relay transmission technologies, wherein we mainly consider the amplify-and-forward relaying method. We will consider two kinds of relay networks, one performing parallel single-directional transmission and the other three-point bidirectional transmission. The former employs multiple relays to form a multi-input multi-output (MIMO) communication channel cooperatively, and the latter employs innovative physical-layer network coding techniques to improve bandwidth efficiency. | en_US |
