| 摘 要： | Turbo码是一种具有接近Shannon编码理论极限性能的并行级连码。阐述了一种性能极为优越的低速率超正交Turbo码,它以带宽为代价,在高斯及衰落信道中的性能均优于普通的Tur-bo码,因此适用于扩频通信的CDMA系统。最后给出了仿真结果。

| Abstract: | Turbo -codes ,Parallel Concatenate d Convolution Codes(PCCC)whose performance in AWGN channel has been shown to be near the Shannon limit.In this paper we describe a low rate super-orthogonal Turbo -code that outperforms the ordinary Turbo -code at the e xpense of bandwidth expansion both in AWGN and especially in fading channels.Thus superorthogonal Tur bo -codes are suited mainly for spread -spectrum applications,such as CDMA system.Simulation resu lts are also presented. |
