Description: Several maximum likelihood MIMO detection algorithm performance and complexity comparison and improvement, introduced the semidefinite relaxation, branch and bound, and the stack of three low-complexity maximum likelihood detection algorithm and its performance and complexity of the simulation analysis , proposed an improved branch and bound, and the stack algorithm, simulation results show that the stack algorithm branch and bound and given a better performance than a half relaxation algorithm, branch and bound algorithm complexity is lower than the stack algorithm and the algorithm for semidefinite relaxation polynomial complexity approximation of the maximum likelihood achieved performance, while improving the algorithm to speed up the convergence rate and reduces the computational complexity and storage space requirements.
