Abstract针对卫星通信中常用的PSK调制,提出一种高效的可覆盖低速率到高速率的卫星测控通信QPSK全数字解调实现方案,并针对解调中所涉及的早迟积分算法和Gardener同步算法进行研究。主要进行系统的频率同步和定时同步的原理分析,建立整个系统的simulink仿真模型,在FPGA平台上进行硬件实现验证,并证明了系统设计的合理性和可行性。
Other AbstractFor PSK modulation commonly used in satellite communications,propose an efficient implementation that can cover lowrate to a high-speed communications satellite monitoring and control all digital QPSK demodulation,and for the demodulation involved in the early-late integration algorithm and Gardener synchronization algorithm to study.Mainly for frequency synchronization and timing synchronization Principle Analysis,establish the overall system simulink simulation model,and test on the FPGA platform,prove the rationality and feasibility of the system design.
