Alternating Adaptive Beamforming System Based on the APL/SR-LMS Algorithms

Beamforming is a wireless communication technique used in telecommunications applications, which is used to separate a desired signal from interfering signals. This technique increases the coverage range and reduces the interference problem, improving the performance of the systems. To achieve this...

This technique increases the coverage range and reduces the interference problem, improving the performance of the systems. To achieve this operation, adaptive algorithms are required. In this work, an alternating structure for beamforming systems is presented, which is composed of two algorithms, the Sign Regressor Least Mean Square (SR-LMS) and the Affine Projection Like (APL) algorithm. The results show that the proposed structure has the best characteristics of the combined algorithms, obtaining an algorithm with a high convergence speed and lower computational cost compared to other algorithms based on conventional convex combinations. El Beamforming es una técnica de comunicación inalámbrica utilizada en aplicaciones de telecomunicaciones, la cual se usa para separar una señal deseada de señales interferentes. Esta técnica aumenta el rango de cobertura y reduce el problema de interferencia, mejorando el rendimiento de los sistemas. Para lograr dicho funcionamiento se requiere de algoritmos adaptativos. En este trabajo, se presenta una estructura alternante para sistemas beamforming, la cual está compuesta por dos algoritmos adaptativos, el Sign Regressor Least Mean Square (SR-LMS) y el algoritmo Affine Projection Like (APL). Los resultados demuestran que la estructura propuesta tiene las mejores características de los algoritmos combinados, obteniendo un algoritmo con una alta velocidad de convergencia y menor costo computacional en comparación con otros algoritmos basados en combinaciones convexas convencionales. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/140 10.37537/rev.elektron.6.1.140.2022 spa FIUBA https://elektron.fi.uba.ar/elektron/article/view/140/284 https://elektron.fi.uba.ar/elektron/article/view/140/293 Derechos de autor 2022 Juan Gerardo Avalos Elektron Journal; Vol. 6 No. 1 (2022); 52-57 Revista Elektron; Vol. 6 Núm. 1 (2022); 52-57 Revista Elektron; v. 6 n. 1 (2022); 52-57 2525-0159 2525-0159 Beamforming adaptive filtering adaptive algorithms convex combination Beamforming filtrado adaptativo algoritmos adaptativos combinación convexa Alternating Adaptive Beamforming System Based on the APL/SR-LMS Algorithms Estructura alternante para sistemas de beamforming adaptativo basada en los algoritmos APL/SR-LMS info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=140_oai
