Constant Modulus Algorithm in Intelligent Antenna

摘要：

Intelligent antenna technology, as one of the important technology in mobile communication field, realizes the beam moving by adjusting the weighted amplitude and phase of every array to change the direction of the array antenna pattern, as the mobile user moves. The beam formation is also called space adaptive filter, which uses the beam which has shapes by some useful information or the signal needed direction to repress the interference which dont need direction. Constant Modulus Algorithm which is one of the important blind algorithm in the intelligent antenna, by Matlab simulation, studying the method of adaptive initialization and adjusting the weighted value in LCDCMA algorithm finishes the improvement of the algorithm, improving the antiinterference ability and the signal-to-noise ratio, so that we can separate good desired signals and jamming signals.
