【摘要】 PSK调制解调器是卫星通信的重要设备,在调制解调器中解调基带算法与工程实现一直是国内研究的重点与难点。主要介绍解调基带部分应用的一些技术和算法,重点对解调器中误差估计的算法进行分析,并提出了1种时钟定时环路的实现方案,以及1种载波锁定检测方法。该方案已经在中、高速调制解调器中经过验证并得到应用。更多还原

【Abstract】 In this paper, some critical technique and algorithms on the application of baseband PSK demodulation are introduced and the error estimate algorithms are analyzed emphatically. Also, a new scheme of clock timing loop and a new carrier locked detector algorithm are proposed. This scheme has been validated and used in the middle-speed and high-speed demodulator.更多还原
