Decoding Algorithm with Fast Hadamard Transform for Channel Quality Indication (CQI) in 3GPP-LTE

摘要：

Channel quality indication (CQI) report is an important element of LTE and has significant impact on the system performance. The encoding method for CQI in 3GPP-LTE is Reed-Muller (RM) code and the transmission quality of CQI can be improved by channel coding with RM code. On the receiver, the contradiction between low latency which is one of goals of LTE and reliability of communication system can be eased up by fast decoding algorithms, among which Fast Hadamard Transform (FHT) is described in this paper. Performance analysis as well as computer simulation of the whole process of CQI coding is also presented.
