應用於音訊群播之FM-RDS收發機設計與製作

隨著傳輸技術的快速發展，對於音訊傳輸來說，目前還是以類比系統為主要的傳輸方法，例如FM廣播系統至目前為止依然採用類比的傳輸方式，雖然現在社會的資訊更新迅速，但目前對於將類比廣播系統，更新為數位廣播系統並沒有真正的必要性，所以類比式的音訊廣播系統還是有無法取代的地位。目前在市場上的FM整合晶片也已經發展成熟，不但設計簡單並擁有價格低廉等特性，當FM晶片可以發射RDS及接收RDS信號之後，也使得FM廣播頻段的使用應用更為廣泛。本論文提出使用FM-RDS晶片的全新應用，並設計與實現具有發射與接收RDS信號之無線收發機，達成自動對頻與群組廣播的功能。並與藍芽技術做特性上的比較，本論文所提出的架構，在音訊特性上比藍芽較佳，也比使用藍芽更為經濟，可以為國內外博物館提供一個良好導覽系統，也可利用於有區域廣播需求的地方，例如：社區廣播與大樓廣播系統等… 本論文所提出之群播架構，未來也可做為短距離的群播教學之使用或應用於家用無線耳機，可更有效率的利用FM的頻譜。由於製作成本低，將來利用音訊無線傳輸與低資料量傳輸兩項特點可延伸更多的應用。

For the audio transmission, it is still transmitted by analog system such as FM broadcast system, even though the transmission technology has developed rapidly. The society's information renewal is fast, but there is unnecessary to upgrade analog broadcast system to digitizing broadcast system. Therefore the analogy-like message broadcast system has the status which is unable to substitute. The FM technology development makes FM chip becomes more mature, fully integrated and lower cost in market. Beside, the use of FM broadcast channel will become more effective when the FM chip could transmit and receive the RDS signal. In the thesis, there proposed the all new application in use FM-RDS chip, design the wireless transceiver which transmit and receive the RDS signal, and realize the function of Auto-pairing and multicasting. There also construct a more effective and better performance audio transmission system than Bluetooth in the thesis. It may provide a good solution for the museum tourism guide and may also use in the place which has the region broadcast demand such as community broadcast and building broadcast system. Because the manufacture cost is low, the architecture of the multicasting in the thesis could be used for the wireless audio and low bit stream transmission. Besides, it also may use for short distance multicast teaching or in the home use wireless earphone.
