This paper presents a comparative study of beam forming techniques using least mean square (LMS) algorithm and its variants, like, normalized least mean square (NLMS) algorithm and sign least mean square (SLMS) algorithm. The accuracy of beam generation toward the direction of arrival (DoA) and null generation toward the interferer, depends on the value of(More)
Smart antenna is one of the key technologies in wireless mobile communication network. Smart antenna generates principal beam towards desired user and null toward undesired interferer. In addition to adaptive beam generation, one main task of this system is to generate beam with lower side lobe level (SLL). This paper describes the beam generation using(More)
Thinned phased array antenna is useful for Radar and satellite communications. Main drawback of phased array antenna is generation of side lobes and grating lobes when the beam is titled from broadside direction toward the end-fire direction. This paper reports the optimization of thinned phased array antenna using genetic algorithm (GA). By varying the(More)
