Turbo码在802.11b协议物理层中的应用研究

Using Turbo Codes in The PHY Layer of 802.11b Protocol

给出用 Turbo码代替现行 80 2 .11b协议中物理层的信道纠错码——卷积码的方法 ,通过性能仿真和译码复杂程度比较 ,验证在该协议的物理层上采用 Turbo码来提高无线局域网的性能是可行的。

The ways of using turbo codes as the channel error control coding of the standard of 802.11b in Wireless LAN instead of convolution codes are described.The decoding complications of both codes are analyzed and the simulation show that the BER performance of the Wireless LAN can be leveled up by using turbo codes in PHY layer.
