    Abstract: 毫米波(millimeter-wave, mmWave)通信已經成為在無線網絡處理上,數據傳輸日益增長的需求下最有前途的技術之一。由於在mmWave 頻帶的傳播特性與微波頻帶相比會有更高的路徑損耗。許多研究提出配備大型天線陣列結合毫米波系統克服。在傳統多用戶多輸入多輸出系統中,每根天線都會配置一個射頻鏈,不幸的是在毫米波系統中的硬體成本和功率約束,使得具有大天線陣列的全數位架構難以實現。近期的文獻中使用混合射頻基頻域系統架構以解決這個問題。在本篇論文中,在回顧近期文獻中的混合預編碼設計後,我們在收發器演算法設計上提出新想法,這個想法能夠更有效地收穫陣列增益,模擬結果顯示,我們提出的算法可以接近多用戶全數位架構的總和傳輸率。
    Millimeter-wave (mmWave) has become one of the most promising technologies to deal with the growing demand for data transmission over wireless networks. Due to the propagation characteristics in the mmWave band, there is a higher path loss compared to the microwave frequency band. MmWave communication combined with massive MIMO technique has been proposed. In traditional multi-user fully-digital MIMO system, every antenna connects to one RF chain. Unfortunately, due to the hardware cost and power constraint, fully-digital architecture with a large antenna array in millimeter-wave systems is difficult to implement. Recent works in the literature advocate a hybrid architecture for millimeter-wave systems to solve this problem.In this thesis, after reviewing the recent literature, we proposed new multiuser hybrid transeiver architecture and algorithms in mmWave systems, and then proposed two designs to harvest array gain. Simulation results demonstrate that our proposed algorithms can approach to the total transmission rate of the fully-digital architecture.
