    4. Bandpass sampling theorem and digital quadrature coherent detection

      帶通采樣定理與中頻採集數字正交檢波
    5. When the cur - cuit resets, the chip remains accepting state, works in burst mode, and adopts dpsk modulation mode. it proceeds quadrature - sampled intermediate frequency signal after the ad9057 has converted, then down - converses, despreads and demodulates. the demodulated baseband signal will be sended into scm to dispose through interrupt

      上電復位后,晶元處于接收狀態,工作在突發模式下,採用dpsk調制方式,將ad9057轉換完的中頻信號進行復正交取樣後下變頻、解擴、解調,通過中斷將解調完的基帶信號送入單片機處理;處于發送狀態時,可將數據擴頻、調制,經ad9768送出。
