摘要
超指数迭代盲均衡算法收敛速度快,但对于相位较为敏感,易造成算法的稳态均方误差大。针对这一不足,利用软判决引导思想对修正的超指数迭代盲均衡算法进行并行处理,在保持算法具有较快收敛速度的同时降低了稳态均方误差。计算机仿真结果验证了所提算法的有效性。
The SEI(super-exponential iterative) algorithm for blind equalization converges fast.But the steadystate MSE(mean square error) of SEI which can't correct the phase rotation of the carrier frequency is large. A SEI blind equalization algorithm based on soft decision-directed is proposed.Simulation results indicate that the proposed algorithm is effective in speeding up convergence and decreasing the steady-state MSE.
