| 摘 要： | 在CMA算法基础上,提出了一种混合的修正恒模盲均衡算法MCMA SDD。新算法对CMA算法进行修正,同时引入软判决思想。理论分析和计算机模拟表明,该算法克服了CMA收敛速度慢、稳态误差大的缺点,同时可以纠正相位偏转。与CMA SDD算法相比,具有更快的收敛速度和更低的稳态均方误差。

| Abstract: | A hybird blind equalization technique is proposed based on CMA.The new algorithm modifies the CMA and brings in soft decision-directed theory.The theoretical analysis and computer simulations demonstrate significant improvement in the convergence rates and the residual error after convergence compared with CMA,the proposed algorithm(MCMA SDD) has the better steady-state equalization performance and faster convergence speed than the concurrent CMA and SDD algorithm. |
