同时实现LD-CELP和EC的研究

Study on coincidence of LD-CELP and EC

本文提出一种将回波抵消器（EC）作为LD－CELP编解码器的部分工作的方法，将EC功能融入LD－CELP编解码器之中。文中讨论了用两片TMS320C30实时实现LD－CELP与EC于一个系统中的可能性。

This paper qives a method to build an integrated LDCELP codec system, in which the function of echo canceller is merged into a LD-CELP coder. The paper also discusses the possibility of using two PMS32O C3O chips to establish a system combining EC and LD-CELP functions.
