摘要

基于W-CDMA的3G移动多媒体通信系统支持灵活、自适应的传输能力，既能提供分组数据业务，又能提供语音业务。移动多媒体通信需要一种能够适应不同码率要求的编码方案。RCPC(率兼容穿刺卷积)码是自适应编码的一个实用解决方案。RCPC代码使用单个速率-1/n卷积编码器/解码器对，发射器和接收器只需要共享一个穿刺表。RCPT(速率兼容的穿孔涡轮)代码可以以与RCPC代码类似的方式使用。本文研究了串联RS-RCPT码和RCPT-HARQ(混合ARQ)方案在W-CDMA中的应用。

Rate compatible punctured turbo coding for W-CDMA

3G mobile multimedia communication systems based on W-CDMA support a flexible and adaptive transmission capability to provide packet data service as well as voice service. Mobile multimedia communication requires a coding scheme that can accommodate varying code rate requirements. RCPC (rate compatible punctured convolutional) codes are one practical solution to adaptive coding. RCPC codes use a single rate-1/n convolutional encoder/decoder pair and the transmitter and receiver only need to share a puncturing table. RCPT (rate compatible punctured turbo) codes can be used in a similar way to RCPC codes. This paper considers the application of concatenated RS-RCPT codes and RCPT-HARQ (hybrid ARQ) schemes to W-CDMA.
