Circle beamforming
WebWe evaluate the performance of adaptive beamforming using uniform circular antenna arrays for wireless CDMA systems. Two types of uniform circular array systems are considered: phased arrays and diversity arrays. For a phased array, the circle of radius of the uniform circular array (UCA) is less than one half wavelength; for a diversity array, … WebThis investigation examines and compares two techniques based on such arrays, the classical delay-and-sum beamforming and an alternative method called circular …
