摘要
Abstract
Due to the high complexity of LTE de-mapping algorithm, a simplified LTE de-mapping algorithm SLLR (Simplified Logarithmic Likelihood Ratio) based on LLR soft-decision is proposed. This algorithm aims to simplify the index calculation and logarithmic calculation by decreasing the complexity during LTE de-mapping. By the simulations of the standard algorithm and the simplified algorithm, the bit error rate and block error rate generated by QAM modulation are compared. The results show that the performance of SLLR algorithm is good for LTE communication system.关键词
