alkej-6	hamed, Ali hussein	تصميم و بناء دائرة معالج دقيق للسيطرة على منظومة التجفيف الضؤي للأسنان	2017	8	.pdf	application/pdf	1938	98	62	It uses an unsupervised adaptive neural network with GHA algorithm to extract the principal components that in turn, are used by Capon method to estimate the DOA, where by the PCA neural network we take signal subspace only and use it in Capon (i.e. we will ignore the noise subspace, and take the signal subspace only). Suboptimal methods are more prevalent than the ML technique when the signal_to_noise ratio and number of samples are both not too small, because the suboptimal methods involve solving only a one-dimensional maximization problem and subspace (signal subspace or noise subspace).	cache/alkej-6.pdf	txt/alkej-6.txt
