Adaptive beamforming will distort monopulse ratio curve and influence angle estimation performance of monopulse system with array antennas. A constrained adaptive beamforming algorithm is proposed, which is implemented in a general side-lobe canceller structure. A reduced-rank blocking matrix is constructed to reduce computational complexity, and additional constraints are introduced to maintain the...
Opinion analysis of network reviews provides a channel to find out the viewpoint of the common people in time, and opinion topic identification, as a significant part of opinion analysis, is aimed to identify the objects for the expressed opinions. This paper proposes an opinion topic identification algorithm in independent domain. The algorithm, based on the mode of opinion topic generation in network...
