碩士 === 國立交通大學 === 電子工程學系 === 85 === IS-54-B是由美國EIA/TIA所制定的一種蜂巢式行動無線通訊標準,在這 標準中定義了基地台( Base Station )與手機( Mobile Station )的無線 電系統與呼叫過程 在本論文中, 我們將討論我們在IS-54行動無線電 話計劃中系統設計的部份,接下來我們會將焦點放在五個硬體,軟體間界面 的部份,進而設計出IS-54基頻測試單板 我們也要特別對語音硬體部份做 詳細的介紹,並將我們原本在EVM 單板上所研發出的VSELP組語作修改,並 應用到我們所發展出的IS-54基頻測試單板 最後, 如何建立測試環境也 是非常的重要的意題,我們將會介紹我們對測試板上各個硬體間的系統測 試方法 IS-54-B is a cellular mobile radio communication standard which is defined by EIA/TIA at April 1992. It specifies both radio-system parameters and call processing procedures between base stations andmobile stations. In this thesis, we will discuss the system design of our IS-54 Mobile Phone Project. Then we will focus on the interfaces amongthe five Hardware and Software parts. We will also focus especially on the detailed design of the speechpart, where I was responsible to port the TMS320C50 assembly codefrom (EVM) to our custom board. Finally, setting up the test environment to test our baseband test board is also an important issue for our project. We willpresent the testing strategies in building the whole system from pieces of hardware components in our test board.
