自适应回波抵消技术是模数模保密机走向实用的关键。详细介绍了如何用TMS320C50实现自适应回波抵消技术。由于使用了本方无话检测和双向通话检测,回波抵消的收敛速度和精度达到了满意的效果。
Adaptive echo cancellation technology is the key to practical modulo-module security. Described in detail how to use TMS320C50 adaptive echo cancellation technology. As a result of the use of the non-words detection and two-way call detection, echo cancellation convergence rate and accuracy to achieve satisfactory results.
