Wave beam forming method based on New-Memetic algorithm

The invention discloses a wave beam forming method of ascending MIMO-SDMA, which relates to the field of wireless communication. The invention provides a wave beam forming method based on a New-Memetic algorithm. Aiming at the defect of the traditional wave beam forming method for working out an optimal weight value based on a gradient method (such as a minimum mean square error algorithm and a linear constraint minimum variance algorithm), the method improves the processes of intersection and variation on the basis of the Memetic algorithm (a mixed inheritance algorithm), thereby enhancing the convergence speed and the local searching capability of the algorithm. The method can search the weight vector optimal value of an antenna array, carry out the self-adapting zero control of an interference direction, also enable a maximum gain main lobe to be directed at the direction of a desired signal and enhance the signal-noise ratio of the system.
