摘要
文中对基于归一化参数的二阶二型软件平方环做了改进,引入变带宽的思想,加快平方环的捕获,并利用MATLAB做模拟仿真,验证其可行性,实验证明该算法能为实时解调MSK信号提供准确的同步信息。
An improvement of second-order square loop based on normalized parameter is presented, combined with the idea of variable bandwidth, the acquisition ability of square loop is promoted. Computer simulation by MATLAB have shown its feasibility, and also practical usage results have proved the algorithm can provide synchronization for real-time MSK signal demodulation actually.
