N2 - In this paper, lattice reduction (LR) aided detection with reduced complexity is developed for the detection of the multiple-input multiple-output (MEMO) systems in timecorrelated channel. The proposed scheme computes the LLL-reduced channel matrix at the present time by using the present channel matrix multiplied with the unimodular transformation matrix of the previous symbol time as the initial value of LLL reduction algorithm. Simulation results show that the proposed scheme can achieve the same performance with significantly reduced complexity. Implementation of the proposed scheme with fixed number of iteration for limited complexity in practical system provides the almost same performance as conventional scheme.
