| 摘 要： | 基于快速Frobenius联合近似对角化（FFDiag）算法,提出了一种步长根据代价函数值大小变化的更新规则,使对角化的更新幅度随信号分离状态自适应变化。算法步长与信号分离状态相结合,具有收敛速度快和稳态误差小双重优点,仿真结果证实了算法的有效性。

| Abstract: | A new variable step-size algorithm for blind source separation based on fast Frobenius diagonalization was put forward in this paper,which had a variable step-size according to the change of the cost function.The new algorithm had the advantages of fast convergence speed and small steady-state error.The simulation results showed that the algorithm was correct. |
