Lattice Reduction Aided Detector with Reduced Complexity Exploiting Orthogonal Structure in Real-Equivalent MIMO Channel

摘要：

In this paper, a low complexity scheme for lattice reduction (LR) is presented in multiple-input multiple-output (MIMO) system, where it finds the reduced basis vectors by taking advantage of the inherent structure of real-equivalent channel. By multiplying the unimodular matrix, which obtained from half structure of real-equivalent channel matrix, another orthogonal structure can be easily obtain the reduced matrix. Using these reduced matrices, we can obtain the reduced channel matrix. Simulation results show that the proposed scheme can achieve the same performance with 70％ computational efforts.
