 DIVERSITY TECHNIQUES AND MULTIPLE ACCESS TECHNIQUES TO INCREASE THE CAPACITY IN 4G LTE


    Author(s):  PRADEEP, G. CHAITANYA REDDY ,G. NAGARAJU  
Abstract

Long Term Evolution (LTE) is developing as a major candidate for fourth generation (4G) cellular networks and is being modified by various cellular providers to increase the capacity and speed of mobile telephone networks. LTE is a part of 3GPP and it evolved from the UMTS technology. User channelization is used to enhance the diversity techniques in time varying channels. The major features that discriminate LTE from other technologies at the air interface are Orthogonal Frequency Division Multiple Access OFDMA for the downlink transmission. OFDMA run into the LTE requirement for spectrum flexibility and enables cost-efficient solutions for very wide carriers with high peak rates. In this paper time variations of the frame are taken into considerations
