Modified iterative sphere decoding algorithm in LTE system

摘要：

　　In the long-term evolution (LTE) system,channel equalization makes compensation to restore the original signal,the paper puts forward iteration sphere decoding algorithm which combines traditional sphere decoding and the improved QR based on the conventional QR decomposition detection algorithm.It can effectively reduce the system complexity.At the same time,in QPSK and 16QAM,the simulation results show that the improved QR iterative sphere decoding algorithm performance is better with higher SNR in AWGN channel.
