在LTE-A中， 高速資料傳輸提供了高品質的影音與快速的檔案存取服務， 為了使高速資料傳輸能夠穩定且可靠，傳輸品質的維持是相當重要的議題。但無線電波從戶外進入室內之後，很容易受到錯綜複雜的室內環境所影響，使得傳輸品質下降，無法達到較高的資料傳輸率。而毫微微基地台(HeNB或Femtocell)正是為了解決此問題而被提出。在本篇文章中， 我們將針對毫微微基地台實體層的規格做簡單的介紹，並且展示我們所設計的傳收機架構。最後，我們利用多核心數位訊號處理器與硬體加速器組成一個軟體無線電平台，並在平台上實現了毫微微基地台，且透過一些測試及程序， 驗證了我們所設計的毫微微基地台能做到即時通訊的能力。

LTE-A provides high-speed data transmission services for high-quality video and fast file transfer. In order to make high-speed data transmission to be stable and reliable, the maintenance of the transmission quality is a very important issue. However, due to the radio waves transmitted from the outdoors into the interior are susceptible to the complex indoor environment, the transmission quality declines and the higher data rate transmission is unachievable. In order to resolve this problem, the HeNB have been proposed. In this article, we introduce the physical layer specifications of HeNB and show the transceiver architecture that
we designed. Finally, we use multi-core digital signal processors and hardware accelerators to form a software defined radio platform and realize a LTE-A HeNB based on the platform. Through some tests and procedures, we verified that the proposed HeNB design achieves the capability of real-time communication.
