有约束的Hartley域自适应算法的应用研究

摘要

通过对有约束的Hartley域自适应算法、频域自适应算法及时域自适应算法用于自适应降噪系统的计算机仿真研究，认为在自适应通信降噪中采用基于Hartley变换的自适应算法较频域自适应算法及时域自适应算法性能更优、降噪效果更好，并在高速信号处理器TMS320C30上开发实现了该算法.实验结果表明，将Hartley域自适应算法应用于通信降噪系统，方法实际可行.%Through a computer emulation study of adaptive alogrithm based onconstrained Hartley-domain, frequency-domain and time-domain applied to cancelling noises in communication,the performance and effect of cancelling noises using the adaptive alogrithm based on Hartley-domain are proved to be better than that of algorithm based on frequency-domain andtime-domain. Then the alogrithm is developed and achieved on the digital signal processor (TMS320C30). The experiment results confirm the feasibility of using the alogrithm based on the Hartley-domain in the system of cancelling noises in communication.
