Complex lattice reduction aided detection for multiuser MIMO systems in dual basis

Different detection technique approach in wireless communication for multi input multi output (MIMO) systems at last ten decades. Lattice reduction aided detectors are also use extensively in MIMO systems. These detectors are introduce and work on the traditional algorithm which was originally base on reducing real lattice bases. In this paper, we use complex lattice reduction processing in dual basis to reduce channel matrix and compare the parameters that affect the complexity of the LLL algorithm for MIMO detection. Through use of the complex lattice reduction in Dual basis, the performances of bit error rate are much improved at 8×8MIMO system.
