摘　　要： 提出一种用于WCDMA-TDD系统的重复迭代自适应智能天线算法。通过在自适应算法中把阵列输入信号和作为参考信号的训练序列重复使用,可以在短训练序列情况下实现较好的收敛,提高通信系统的传输效率。对LMS算法中全训练序列重复迭代和滑动窗口重复迭代算法进行了仿真,结果表明,在有限训练序列时该算法比传统LMS算法更好地逼近最佳解。 A repeat iterative adaptive smart antenna algorithm for WCDMA-TDD systems is proposed. The array inputs and the training sequences (midamble) as referent signals are used time after time in the iterative adaptive algorithm. A good convergence can be achieved in case of short training sequence, and the transmitting efficiency in the communication systems can be improved. The simulated results through the full midamble repeat LMS algorithm and the slip window repeat LMS algorithm, demonstrate that the proposed method can obtain better results in case of short training sequence.
