摘要 无线 ATM能通过标准的 ATM网络应用接口，为多种移动终端提供综合宽带业务的传输和交换。研究了适用于无线 ATM的 Turbo码，对 Turbo码与卷积码的性能进行了比较，并且对不同编码效率下 Turbo码的纠错能力进行了仿真研究。 Wireless ATM is intended to provide integrated broadband services to a variety of mobile terminals via a standard ATM network API. This paper designs a Turbo code used in wireless ATM. The performance of Turbo code and convolutional code is compared. It also provides the simulation of two kinds of Turbo codes.
