Abstract

Wideband code division multiple access (WCDMA) is currently being extended into high-speed downlink access (HSDPA) and high-speed uplink packet access (HSUPA). The continuing research of next generation communication proposed by 3GPP is named long term evolution (LTE). The main goal of LTE Release is to offer high peak downlink and uplink rates by the use of Orthogonal Frequency-Division Multiple Access (OFDMA) that attributes a very flexible multi-user bandwidth, high spectral efficiency and scalable bandwidth. The benefit of LTE is the fact that it offers higher data rates in both uplink and downlink and enhances the services for the terminals. A notable fact is that several WiMAX projects have been reoriented toward Long Term Evolution (LTE), mainly aimed at increasing performance. In this paper the challenge of scheduling user transmissions on the downlink of LTE cellular communication system is discussed. Various results show that the system performance improves with increasing correlation among OFDMA subcarriers.
