摘要：

This letter presents the design and optimization of a four-dimensional (4-D) time-modulated linear array to be used in harmonic beamforming-based femtocell cognitive radio network. A novel mutated invasive weed optimization (MIWO) algorithm, where remarkable performance enhancement is achieved especially in the case of problems involving higher dimensional search space through attainment of simultaneous exploration and exploitation, is introduced in this purpose. Moreover, a subarrayed approach is adopted to gain control over beam direction of the main band as well as all the harmonics being used. The reduced search range for each subarray is analytically determined to make the MIWO search faster and more effective. © 2002-2011 IEEE.
