Abstract:	隨著5G-NTN以及星鏈的發展，低軌道衛星通訊成為熱門的研究項目。而衛星對地端的閘口(Gateway)是連接用戶到中央伺服器的骨幹網路連接口，對資料傳輸帶寬有極大的要求，因此通常使用高頻率的波段作為載波。而Ka波段通訊酬載，在提供高速數據傳輸能力的同時，通常對功耗跟衛星載體空間有一定的要求，主要適用於較大的衛星。因此在此研究中，專注於設計和實現一種專為CubeSat上的Ka波段微型軟體定義無線電（MSDR）。通訊協定符合DVB-S2標準，具有高傳輸容量以及可變傳輸率等特色，以因應不同的通道環境，另外也實現了線性階頻率調制（LSFM）模式，提供超低發射功率下的可靠傳輸。此外，該研究基於Xilinx MPSoC以及ADI ADRV9009作為基頻處理單元，並搭配Ka/K波段的升降頻以及功率放大器，模組化軟硬體設計可輕鬆應用於未來的任務。此SDR為低地球軌道（LEO）中的CubeSat星座提供寬頻通信的可能性。;Ka-Band communication payloads, enabling high-rate data transmission, typically require higher power consumption, are mostly more suitable for larger satellites. This research focuses on the design and the implementation of a miniature software-defined radio (MSDR) specifically tailored for Ka-band communication onboard CubeSats. The communication system aligns with the DVB-S2 standard for high transmission capacities, and incorporates the linear-step frequency modulation (LSFM) for robust transmission. Additionally, the modular software design can be easily adopted for future missions. The proposed Xilinx MPSoC-based SDR opens possibilities of broadband communication for CubeSat constellations in low Earth orbits (LEOs).
