A New Modified Variable Steps Size Griffiths Beam Forming Algorithm with Feedback Loop
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Antenna array is the set of antenna elements with each antenna element of type dipole separated by a distance. In this work a new algorithm is described which is combination of Variable Step Size Griffiths(VSSG) along with Speed Management , Convergence Management Module which increases the accuracy of beam forming algorithm as well as improve the convergence of the algorithm. The proposed method is compared against existing beam forming algorithms namely LMS, RLS, Griffiths and Variable Step Size Griffiths. The algorithms are simulated for various cases Low RF Sources and Single Interference, Large RF Source and Single Interference, Low RF Sources and Multiple Interference angles and finally for the case of Large RF sources and Multiple interference angles.
