2、 MFL Abdullah, AZ Yonis AbstractLTE-Advanced (Release 10) is a preliminary mobile communication standard formally submitted as a candidate 4G systems to the ITU-T. It is being standardized by the 3rd, Generation Partnership Project (3GPP) as a major enhancement of the 3GPP Long Term Evolution (LTE-R
3、elease 8) standard, which proved to be sufficient to satisfy markets 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 component
4、s), and heterogeneous networks (relays, picos). This paper presents a study on evolution LTE toward LTE-Advanced in terms of LTE enabling technologies (Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output (MIMO). This paper also focuses on LTE-Advanced technologies MI

INTRODUCTION Mobile communications has become an everyday commodity. In the last decades, it has evolved from being an expensive technology for a few
6、selected individuals to todays ubiquitous systems used by a majority of the worlds population. From the first experiments with radio communication the road to truly mobile radio communication has been quite long. To understand the complex mobilecommunication systems of today, it is important to understand where they came from and how cellular systems have evolved. The task of developing mobile technologies has also changed, from being a national or regional concern, to becoming an incre
