In this study, we compare the performance of three null steering techniques using uniform linear array. These techniques include Null Steering without using Phase Shifters, Null Steering by Decoupling the Real Weights and Null Steering by Decoupling the Complex Weights. The evaluation criteria of these techniques is based on the bases of different parameters i.e., null depth, main beam width, side lobe levels, number of steerable nulls, computational complexity and number of sensors used in the array. The validity and effectiveness of these techniques is reflected by the resultant radiation pattern of the array.
Key words: Adaptive beamforming, independent null steering, linear arrays, null steering, , ,
