WCDMA中基于反哈德马德变换的TFCI译码方案

摘要

在WCDMA中，TFCI（TransportFormatCombinationIndicator，传输格式组合标识）非常重要。WCDMA中TFCI的编码有两种方案，一种是在正常模式下，另一种是在分裂模式下。已有的穷举法译码方法具有效率低的缺陷，该文提出利用反哈德马德变换进行高效TFCI译码的方案。仿真表明了该译码方案的有效性。%TFCI is very important in WCDMA. In 3GPP (Release 4), there are two coding schemes oI Tr- CI, one scheme is in normal mode, and another scheme is in split mode. In this paper, we propose a deco- ding scheme for TFCI by using inverse hadamard transform (IHT) and simulations show that the decoding scheme is very convenient.
