The optimization of some key parameters using MUSIC algorithm enables improved estimation of the AOA. The Minimum Mean Square Error (MMSE) is implemented in the algorithm of adaptive beam forming. The ability of enhancing the beam pattern (main lobe direction and the beam width) is achieved by choosing different values of relevant parameters. It has been found that increasing the number of array elements, increases the accuracy of beam-forming and more focusing of the beam is realized.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/3/65/996/489/3659964891_b.jpg", "price_data" : { "retail_price" : "51.00", "online_price" : "51.00", "our_price" : "51.00", "club_price" : "51.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
