摘　　要：传统RLS算法由于复杂的矩阵运算而无法满足实时性要求,在传统RLS算法的基础上,提出基于简化型RLS算法的延迟改进型噪声抵消系统模型,并将此模型应用于TMS320C5509DSP的语音处理平台上实时实现。实验证明,该模型滤噪性能较普通的LMS自适应滤波器有显著提高,且可满足实时性要求。The normalized RIS algorithm has the drawback of complicated matrix computations and cannot satisfy the real-time request. This paper presents an improved delay model of noise cancellation system based on simplified RLS algorithm. By realizing the model on the platform of speech processing system which uses TMS320C5509 DSP chip, it is proved that the performance of this model is obviously superior to that of the LMS algorithm, and can satisfy the real-time request.
