In this paper, we studied the massive multiple-input multiple-output (MIMO) system performance with N antenna users and streams can be multiplexed per each user. The spectral efficiency (SE) of uplink and downlink expressions is derived for any N antenna users and these achievable using estimated channels and per user basis minimum mean squared error(More)
An auto adaptive neuro-fuzzy segmentation and edge detection architecture is presented. This system consists of a multilayer perceptron (MLP)-like network that performs image segmentation by adaptive thresholding of the input image using labels automatically pre-selected by kernel based fuzzy clustering technique. The proposed architecture is feed forward,(More)
Quantum Cellular Automata (QCA) is a new technology in nanometer scale to support nanotechnology. QCA is very effective in terms of high space density and power dissipation and will be playing a major role in the development of the Quantum computer with low power consumption and high speed. This paper describes the design and layout of a 2-bit ALU based on(More)
Spectral efficiency (SE) of massive multiple-input multiple output (MIMO) systems with a very large number of antennas at the base station (BS) considering for space constraint antennas are investigated in this paper. In literature, fixed spacing inter-element were considered, the number of antennas increases with a fixed total distance in a practical(More)
