SOPHISTICATION TECHNIQUES OF FOURTH GENERATIONS IN NEOTERIC MOBILE LTE AND LTE-ADVANCED

Long Term Evolution (LTE-Advanced) is a preliminary mobile communication standard formally submitted as a candidate for 4G systems to the ITU-T. LTE-A is being standardized by the 3rd Generation Partnership Project (3GPP) as a major enhancement of the 3GPP Long Term Evolution (LTE-Release 8) standard, which proved to be sufficient to satisfy marketa€ s demand. The 3GPP group has been working on different aspects to improve LTE performance, where the purpose of the framework provided by LTE-Advanced, includes higher order MIMO, carrier aggregation (carriers with multiple components), peak data rate, and mobility. This paper presents a study on LTE evolution toward LTE-Advanced in terms of LTE enabling technologies (Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output (MIMO)), and also focuses on LTE- Advanced technologies MIMO enhancements for LTE-Advanced, Coordinated Multi Point transmission (CoMP).
