| 摘 要： | 提出针对一种特殊干扰信号的自适应抵消器改进算法。它既能有效地进行噪声抵消，又在一定程度上加快收敛速度，从而提高自适应抵消器在这种干扰环境下的性质。文中通过严格的理论推理，证明这种算法的可行性和优越性。计算机仿真结果表明，利用改进算法得到的抵消器输出结果，明显优于传统算法所得的结果。最后指出，这种改进算法在范围上的特殊性。

| Abstract: | Directing against a special interference signal, an improved algorithm is presented for the use of an adaptive canceller. By which not only the noise can be effectively cancelled but also the convergence can be speeded to some extent. The performance of adaptive canceller is thus improved under this interference environment. The feaslbility and the superiority of this algorithm are proved by strictly theoretical inference. As indicated by computer simulation, the output result of canceller obtained by using improved algorithm is obviously better than that obtained by conventional algorithm. The particularity of this improved algorithm is pointed out finally |
