PARTICLE SWARM OPTIMIZATION OF DIPOLE ARRAYS FOR SUPERIOR MIMO CAPACITY

The particle swarm optimization (PSO) technique is employed to design MIMO arrays for superior capacity. A channel model based on the method of moments solution of the electric field integral equation is utilized with PSO for arrays of dipole elements. Freestanding and printed dipole arrays are analyzed and optimized. Their adaptive performance in the MIMO channel is compared. Numerical results in the form of mean capacity, including comparisons with genetic algorithm results and measurements, are given. (C) 2008 Wiley Periodicals, Inc.
