Abstract: The Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing Technology (MIMO-OFDM) may become an inevitable contender for being deployed in almost all types of future generation wireless communication systems for attaining high spectral efficiency at extremely high throughput. The technical constraint in realization of such systems is high computational complexity of the detector when designed for higher order MIMO with 64-QAM and 256 QAM. This paper presents design and development of a novel detection algorithm based on Adaptive Sphere decoding technique to realize a low complexity 4x4 MIMO-OFDM receiver. The new algorithms are tested with LTE standards on MATLAB platforms, have shown significant reduction in computational complexities in terms of number of nodes traversed, Flops, Complex Multiplications, etc, and still performing at par with optimal detectors. The proposed detection algorithms may serve as one of the strong contenders to be deployed in future genera

Abstract: The word around us is full of physical variables that are constantly changing. If we can measure these variables and represent them as a digital quantity, then we can equally record, restore, retrieve, re-organize, manipulate and use them in some other ways in quantities imaginably through information dissemination and services. To tackle the battle imposed upon by the “Omnipotent” National Union Catalogue in Nigeria, the professional librarians have to equip themselves with the mentality of keeping abreast of current developments in the library networking technologies with determination and develop their own “Home-made Schemes” that would form a framework for a National Union Catalogue if not for Africa as a whole but for Nigeria as a Nation. This paper illustrates the importance of cataloguing and classification in organizing our libraries and attempts how the professional librarians can brainstorm together to develop a framework of a comprehensive list of a National Union Catalogue
