Performance Optimization for Long Term Evaluation (LTE) Networks

Abstract

with the aim of more than twice the capacity over High-Speed Packet Access. The chosen multiple access for uplink is Single Carrier FDMA, which avoids the intra-cell interference typical of CDMA systems, but it is still sensitive to inter-cell interference. As a result, the role of the power control becomes decisive to provide the required SINR, while controlling at the same time the interference caused to neighboring cells. This is the target of the Fractional Power Control (FPC) algorithm lately approved in 3GPP. In this thesis, the OLPC is studied in detail to obtain a reference performance, and then all techniques are proposed with the aim of improving it. All techniques are implemented on a static simulator that models slow variations. The comparison of the result among the different techniques is carried out by considering key performance indicators like the cell outage and cell throughput.
