Background/objectives: The objective of the study is to increase the resolution and radiate sharper beam towards the user in mobile communication using Smart Antenna. Methodology: The Conventional and Subspace Algorithms from the literature are studied and simulated in MATLAB so that the foundation is laid for better detection of algorithms and radiation formation. The results are explained for varying number of antenna elements and mobiles sources placed close to far. Findings: The classical direction of arrival algorithms namely CAPCON, Maximum Entropy Method, Maximum Likelihood Method are used to find the direction of mobile users based on the computation of the power spectrum. Several methods namely Least Mean Square, Griffiths Method, Variable Step Size Griffiths and Recursive Least Square are used to form the main beam for the user detected by the direction of arrival algorithms. Novelty/improvements: In order to take further the research on enhancing the resolution and having a higher convergence rate with reasonable step size, this paper presents the well-known conventional and modern algorithms from the literature. The results are simulated are well described for performing parameters.

In highly dynamic scenes, beamforming can alleviate satellite signal attenuation and distortion caused by null widening. In this article, a beam steering scheme based on strapdown inertial navigation system (SINS) aid is proposed.Firstly, the Hermite interpolation algorithm is used to calculate satellite position coordinates to reduce the amount of calculation. On the other hand, the satellite position coordinates are converted to the antenna coordinate system, and the beam direction is calibrated based on the attitude angle measured by the SINS to ensure the optimal beam gain. Finally, the proposed scheme is verified through a simulation, and the influence of SINS measurement errors and interpolation errors on the beamforming performance is evaluated. The simulation results show that the proposed method can effectively improve and stabilize the signal-to-noise ratio and reduce the influence of anti-interference processing on satellite signals close to the interference direction in dynamic scenes.
