  • In order to evaluate and improve present precoding scheme in MIMO space communications, Zero-Force (ZF) and Minimum Mean Square Error (MMSE) criterion based joint Lenstra, Lenstra, Lovász (LLL) Lattice Reduction (LR) nonlinear Tomlinson-Harashima (TH) precoding algorithm is simulated and analyzed. At the same time, according to the basis of TH precoding, an improved lattice reduction based TH precoding is proposed by improving the singularity of the channel matrix. Simulation results indicate that the performance of MIMO precoding with MMSE criterion is better than that with ZF criterion. In addition, the proposed LLL lattice reduction based TH precoding has still obtained much better performance gain than traditional ones while a little more complexity is reduced by the LLL LR method. Therefore, it can be used in the precoding applications and so on in the multiple antenna MIMO space transmission.
