In order to solve the problem of high computation complexity of LLL algorithm in MIMO detection,the LLL algorithm's parameter δ which influences the column exchange process is analyzed theoretically and experimentally.In addition,the influence of δ on the computation complexity,orthogonal defect and BER(Bit-Error Rate) performance in MIMO detection are also analyzed.Numerical results show that the LLL algorithm parameter δ=0.75 is the best value in MIMO detection system.
