Abstract

The Cocktail Party Problem solution is described as being the responsibility of isolating the voice signal in a noisy environment. Two popular methods for resolving this issue are blind source extraction and the Wiener filtering procedure. The blind source extraction approaches like fastICA, JADE and efficient fastICA are useful for extraction data from the mixed signals. The classical optimization techniques such as genetic algorithms or particle swarms for blind source extraction are mostly founded on the gradient and need the objective function, so the using of these techniques is very restricted. In the recent studies, the classical blind source separation techniques will not give the perfect solution for the cocktail parity problem. These methods struggle with convergence speed and accuracy issues as well. In order to enhance the separation process and get over these issues, this work adopted the glowworm swarm technique based on kurtosis as the objective function. The results show that the proposed technique produces good separation. The original and estimated signals are compared for similarity using the cross-correlation function.

Abstract

Al-Furat Al-Awsat Technical university ATU, is one of the newly established academic institutions in Republic of Iraq. Since its emergence in 2014, presently the university is keen to secure its position among other internationally to be a well recognized academic institutions, thereby addressing all sustainable goals and related challenges in its futuristic development schemes. These include developing all existing educational programs and schemes, developing in campus faculty infrastructures, implementing alternative energy resources, developing waste managements, enhancing potable water conservation existing projects and evolving existing transportation structures. This current manuscript highlights in depth all the above indicated developments schemes thereby examining their implementation stages and addressing all associated challenges that face the university. It also looks at its potentials and capabilities to overcome such issues.
