This paper provides the information regarding the improvement in capacity and signal strength with the implementation of adaptive beamfoming algorithms (LMS and SMI) in adaptive antenna arrays.In this a beamforming algorithm is analyzed for flexible side lobe adjustment. The algorithm places a very low side lobe level over a large width in the beam pattern. The convergence of this algorithm is ...

-This paper discusses the deployment of Genetic algorithm optimization method for synthesis of antenna array radiation pattern in adaptive beam forming. The synthesis problem discussed is to find the weights of the antenna array elements that are optimum to provide the radiation pattern with maximum reduction in the side lobe level. This technique proved its effectiveness in improving the perfo...

Contralateral deviation of the eyes was sustained for a week in a patient with discrete subcortical frontal lobe haematoma. When deviation recovered, ipsilateral saccades were hypo-metric and saccadic latencies were prolonged in both horizontal directions. Smooth pursuit was paretic during tracking toward the side of the haematoma. Pursuit gain was higher during tracking to the contralateral si...

This paper discusses a far-end crosstalk (FEXT) canceller for twisted-pair transmission. Many twisted-pair systems such as fiber-to-the-curb, very high-speed digital subscriber line, and high-speed LAN systems, use frequency-division duplexing (FDD) for duplex transmission. It is shown that the maximum reach of FDD twisted-pair system is limited by the performance of its upstream channel, which...

The transfer function-generalized sidelobe canceller (TF-GSC) is one of the most popular structures for adaptive beamformer used in multi-channel speech enhancement. Although TF-GSC has shown decent performance, a certain amount steering error inevitable, which causes leakage components through blocking matrix (BM) and distortion fixed (FBF) output. In this paper, we propose to suppress leaked ...

Synchronization is a fundamental characteristic of complex systems and a basic mechanism of self-organization. A traditional, accepted perspective on epileptiform activity holds that hypersynchrony covering large brain regions is a hallmark of generalized seizures. However, a few recent reports have described substantial fluctuations in synchrony before and during ictal events, thus raising que...

High resolution RADAR images of contiguous targets like vehicles on road often suffer from side lobe enhancement. This leads to false alarm in target detection and degradation in image quality. In this paper, adaptive CLEAN algorithms are introduced to eliminate side lobe enhancement and significantly improve the target detection with better image quality. The effectiveness of the CLEAN algorit...
