  1. The carrier wave is modulated directly by the baseband signal at several frequency point in l band and s band. firstly, this paper clarifies the theory of i / q modulation, elaborates evm and acpl, and analyzes the effect of amplitude and phase unbalance and dc offset on evm. secondly we review the basic principle of phase locked loop and it ’ s composing parts, including the basic conception and design method of pll frequency synthesizer, especially introduce the charge pump pll frequency synthesizer in detail

    首先,在闡述i / q正交調制基本原理的基礎上,通過對誤差矢量和鄰近通道功率泄漏的詳細分析,定性、定量地討論了各種非理想電路因素(如相位不平衡、度不平衡、直流偏差等)對調制器性能的影響;其次,介紹了相環的工作原理和基本組成部分,包括相環的設計和環路濾波器的設計,特別詳述了電荷泵相頻率源;第三,介紹了採用直接調制技術擬衛星信號的射頻前端的設計;最後,對整個直接射頻調制系統進行測試,結果基本上達到了課題要求。
  2. The paper compares some algorithms on rs decoding, makes improvements based on the me algorithm, removes the modifying step in decoding truncate rs code, corrects unsuitable statements in the related papers, and parameterizes the rs decoding module, reducing its area by 20 %. the paper overcomes the signal integration problem in multi - clock design, greatly lowers the phase jitter without area increase, introduces pll to adjust rate for the first time, and parameterizes the module

    本文比較了實現rs解碼的幾種演算法,並在me演算法基礎上進行改進,創造性的去掉了縮短碼解碼中的校正環節,糾正了有關論文中的不當論述,並將rs解碼塊進行了參數化設計,同時也將rs解碼的規縮小了20 ;克服了多時鐘設計中的信號完整性難題,在沒有增加塊面積的條件下,大降低數據的相位摘要抖動,首次引入相環來調整速率。
  3. In the control loop, the phase - lock loop was used to trace the operating frequency, the vibrating - amplitude loop was used to control the driving influence, the compensate control loop was used to adjust balance, and the measuring loop was used to measure. with the simulation charts of various subsystems, the system parameters were designed

    在控制迴路中,利用相迴路來追蹤工作頻率,用振控制迴路來控制驅動力,用補償控制迴路調節平衡,用感測迴路進行感測,並且利用各分系統的擬圖設計出系統參數。
