| Abstract: |
| Based on minimum mean square error criterion,the problem of solving the weight of adaptive beamforming is represented as a multi-objective optimization model,and a proposed particle swarm optimization algorithm is used to obtain the optimal weight vector of the array.The improved particle swarm optimization algorithm introduces the dynamic neighborhood topological structure,and adaptively adjusts the domain search range of the particles to avoid the particles from falling into the local optimum.The simulation results showes that the convergence rate of the algorithm is better than the traditional algorithm. |
