The basic requirement of the adaptive algorithm is to eliminate the interference and increase the Signal-to-Interference-plusNoise Ratio (SINR). The efficiency of the adaptive algorithm depends on the accurate estimation of the spatial covariance matrix. Generally the data used to estimate the covariance matrix should not contain any signal of interest, if so adaptive algorithm eliminates the signal also along with the interference. Diagonal loading is one of the most widely used and effective method to improve robustness of adaptive beamformer, but selecting the diagonal loading value has become a key aspect. In the absence of complete knowledge of signal characteristics and continuously changing environment, fixed diagonal loading method may not give desired performance, hence the adaptive method is essential. In this paper we propose adaptive diagonal loading method for Minimum Power Dist...
