摘要
WCDMA系统重要优势之一是支持多速率和多业务,使不同传输速率的信道复用到一个编码复合传输信道(CCTrCH)上,传输格式组合指示(TFCI)至关重要。文章对正常模式码字的编码和经典大数逻辑译码算法进行研究,根据TFCI编码特点,给出一种最大相关和大数逻辑译码相结合的译码算法,该算法能降低TFCI的误码率,是一种简单有效的方法。
One of the major advantages of WCDMA system is that it supports multi-rate and multi- service, and Transport Format Combination Indicator plays an important role in multiplexing different speed channels to one Coded Composite Transport Channel. After studing the normal mode codes and classical majority-logic decoding algorithm, an improved decoding algorithm, which integrated max correlation and majority-logic decoding, was given based on the characteristics of TFCI coding. This algorithm is a simple but effective approach, able to reduce the error rate of TCFI.
