摘要:
Turbo码是一种前向信道纠错码。它比卷积码有更高的译码增益,译码性能几乎接近Shannon理论极限,从而在信道的传输中具有更高的可靠性,适用于传输速率较高的业务。它优越的性能引起了人们广泛的关注。但由于Turbo码译码算法相对复杂,造成的译码时延比较大,Turbo码往往不适用于对实时性要求高的业务。WCDMA系统中使用Turbo码传输32khps及以上的业务。文中介绍了WCDMA中所采用的Turbo码编码结构中的质数交织器,利用MATLAB仿真,分析交织长度对Turbo码性能的影响,并通过与其他类型交织器性能上的比较,验证了质数交织器在WCDMA系统中的性能优势
Abstract:
Turbo coding is a kind of forward error correction coding method that outperforms convolutional coding in terms of BER and is close to the Shannon limit. So Turbo coding is more reliable in TrCHs, and it is applicable to applications that require high bit rate. Its excellent performance has drawn lots of attention. However, the decoding algorithms for Turbo coding are so complicated that takes a lot of time. So Turbo coding is not fit for real-time applications. Turbo coding is usually used for applications that require 32kbps or higher in WCDMA system. It introduces the prime interleaver in Turbo encode of the WCDMA system, using MATLAB simulation, analyses the influence of the interleaving length for Turbo code performance, and compared with the other types of interleavers, proves the performance advantages of the prime interleaver in WCDMA system
