On the basis of simplified maximum likelihood estimation algorithm, a novel time and frequency synchronization scheme in TD-LTE system is proposed This scheme can get time synchronization and estimate the frequency offset correctly, and has the advantage of effectiveness and low complexity.
Channel estimation is critical to receiver performance in the long term evolution (LTE) system. Reference signals are interspersed with data signals among the subcarriers to aid channel estimation. Linear minimum mean square error (LMMSE) channel estimation is an efficient approach to estimate the knowledge of channel with high complexity. LMMSE based on singular value decomposition and partitioning...
In this article, a new method to design the flexible-length S-random interleaver is proposed for storage optimization in a turbo coding system. In this method, the high-spread property s-random interleaver is constructed by selecting appropriate position and element that can improve spread property of interleaver in each iteration in which length of interleaver is increased. Using this method, interleavers...
