本論文是以手持式的GPS導航產品做一研究對象，此一平台有GPS導航、DMB數位多媒體廣播接收和GPRS的資料封包傳輸 等功能。先分別對GPS、DMB、GPRS作測試，量測各個功能的C/N值，然後再看DMB對GPS及GPRS是否有所干擾，以此類推將測試所得到的數據經處理及分析，來對此在未來產品上能有解決問題的方法。 This thesis deals with the study of series products of global positioning system (GPS).The integrated analysis of GPS navigation, digital multimedia broadcasting (DMB), and general packet radio service (GPRS) is presented. The operations of GPS, DMB, and GPRS are performed and measured, respectively, to get their corresponding C/N values to check if the operations of GPS and GPRS are affected by DMB, so as to find out how the video improvement of associated GPS products can be achieved.
