| 摘 要： | 针对SPRLS算法在误差较小时收敛速度慢的问题,利用误差梯度信息对自扰动项进行修正,从而提出了一种适合智能天线的改进型SPRLS算法。通过仿真试验,验证了在信道发生突变时,改进后的算法在有限迭代次数下,具有比SPRLS算法更好的收敛速度和更小的均方误差。同时该算法在复杂度上代价较小,具有较好的实用性。

| Abstract: | In order to overcome the drawback of SPRLS algorithm that have slow convergence rate when error is small, we use the information of error grads to modify the self-perturbing term and present a new modified SPRLS algorithm which is applicable to smart antenna. Theory and computer simulations show that the modified algorithm, which is simple and practical, has faster convergence rate and smaller square error than SPRLS algorithm. |
