Improving the VSSNLMS adaptive beamformer for adaptive antenna systems

A new configuration for the adaptive beamforming technology has been presented in this research work. We modified the structure of the uniform linear array (ULA) in such a way that a correct beam can be formed uniformly for all azimuth angles. For ULA composed of M antennas, we place two extra elements on the top and the bottom of the configuration of the ULA (at the array axis).  Then, we develop the mathematical model or the same. To investigate the efficacy of the proposed antenna configuration, we deploy the VSSLMS beamformer. The new beamformer is compared with the well-known LMS and the MLMS adaptive beamformer. Computer simulations are provided in the result section of this paper to validate that the new beamformer has enhanced convergence rate and high data transmission compared to the LMS and the NLMS methods. Also, the new method has the same performance for middle angles, near boresight and array end fires which is not possible for the LMS and the NLMS method using a ULA
