| 摘 要： | 二进制FSK是数字通信中应用较广的一种调制方式.传统的解调方法在抗噪声性能和运算复杂度之间存在矛盾.文中针对2FSK解调中这个问题,在分析传统方法的基础上提出了一种改进的正交差分解调算法和基于滑动积分的联合定时算法.仿真表明,提出的解调算法具有更好的灵活性,定时算法在性能和实现复杂度上取得了较好的折衷,解调性能良好.

| Abstract: | 2FSK is a widely used modulation in digital communication.There exists the conflict between antinoise performances and operation complexity.An improved quadrature differential demodulation algorithm and a timing Synchronization algorithm based on 2FSK demodulation are proposed.The simulation results show that the proposed demodulation algorithm is more flexible and the timing Synchronization algorithm makes good tradeoff between performance and implementation complexity.The demodulation is correct and excel... |
