| 摘 要： | 对比研究了3种常模类盲均衡算法在水声信道均衡中的收敛性能，这些算法包括传统的常数模算法、归一化常数模算法和解相关常数模算法。通过仿真对各算法性能进行了分析。仿真结果表明，在算法剩余均方误差非常接近的情况下，解相关常数模算法和归一化常数模算法快于传统的常数模算法。

| Abstract: | Three constant modulus type blind equalization algorithms are discussed comparably, they are constant modulus algorithm, normalized constant modulus algorithm, and decorrelating constant modulus algorithm. Performances of these three algorithms are analyzed by computer simulation. The simulation result shows that the decorrelating algorithm and the normalized constant modulus algorithm converge faster than the constant modulus algorithm. At the end of the convergence,all these three algorithms show very similar MSE performance. |
