【中文】 本發明為一種調頻連續波(FMCW)雷達通訊方法與系統,該方法或系統用於在第一物件及第二物件間通訊,其中該第一物件具有訊號傳送裝置及雷達接收裝置。該方法包含由該訊號傳送裝置中的訊號傳送模組執行:將含有調頻連續波的啁啾(chirp)訊號之待傳送訊號切割成D個子訊號;使各該子訊號攜帶頻率索引調變符碼(FIM symbol);根據該FIM符碼決定傳送該子訊號時所佔據的特定資源區塊(Resource Block, RB);以及利用該特定資源區塊傳送該子訊號,俾達到提升該待傳送訊號之系統傳輸速率。 【英文】 A frequency modulated continuous wave (FMCW) radar-communication method and system are provided, the method or system is applied to communicate between a first object and a second object, wherein the first object has a signal transmission device and a radar receiving device. The method includes a signal transmission module of the signal transmission device to perform: dividing a transmitting signal which contains a FMCW chirp signal into D sub-chirps; setting each of the sub-chirps to carry a frequency index modulated (FIM) symbol; deciding a special resource block (RB) for being occupied by the sub-chirp according to the FIM symbol; and transmitting the sub-chirp using the special resource block for enhancing a system transmission rate of the transmitting signal.
