Adaptive beamformers will degrade severely when the array weights cannot adapt as fast as the environmental changes, especially when unexpected interferences exist. Low sidelobe levels can increase the ability to suppress the white noise and unexpected interferences. The adaptive beamforming with low sidelobe levels is transformed into a weighted pattern synthesis problem. This weighting function...
To increase the capacity of mobile communications, it is important to accurately estimate the power and the direction of arrival (DOA) of source. An efficient algorithm is proposed for this purpose. A cost function is optimized by using the particle swarm optimization (PSO). To accelerate the convergence of the fitness function of PSO, the inertia weights of particles are different from each other...
