针对符号递归常数模算法稳态误差大的缺点,提出一种时变步长符号递归常数模算法。水声信道仿真结果表明,与传统的常数模算法及符号递归常数模算法相比,变步长符号递归常数模算法收敛速度快,而且剩余均方误差更低,对水声信道具有良好的均衡能力。 Aiming at the shortcomings that the steady-state error of symbol recursive constant modulus algorithm is large, a time-varying step recursive constant modulus algorithm is proposed. Acoustic channel simulation results show that compared with the traditional constant modulus algorithm and the symbolic recursive constant modulus algorithm, the variable step size symbolic recursive constant modulus algorithm has the advantages of fast convergence, lower residual mean square error, Good balance.
