LTE network performance evaluation based on effects of various parameters on the cell range and MAPL

Abstract

These days long term evaluation (LTE) is considered the common mobile technology around the world and there is a need to maximize the network performance to satisfy the increased demand in terms of the cell capacity and coverage. These are many parameters in the network configuration and in the surrounded environment, which have great effects on the network performance. Examples of parameters are the system overhead rations, the required capacity of the network, neighbor cell load, and link budget parameters. The determination of the optimum configuration parameters, which achieve the best network performance, is a main step in the planning process in addition to it is continuous step in network optimization phase. In this study, the effects of some parameters will be investigating to get the best parameters that achieve the best network performance in terms of capacity of the cells and coverage area. The study will start by discussing introduction about LTE network components and protocols, and then the main parameters of the protocols will be revising. The study will display the results of changing many parameters related to LTE protocols and surrounding environment parameters on the LTE network performance.

Transmission performance in compressed medical images using turbo code

“…LTE channel coding: among the LTE system advantages, there is the benefit that no recommendations or limitations apply to the digital algorithms used when coding the channel. This gives a certain degree of freedom to choose the algorithms with the best compromise between good performance and least complexity [29]. The (turbo-code) algorithms principle [50], like any error correcting code, is to introduce redundancy in the message in order to make it less sensitive to the noises and disturbances undergone during transmission.…”

“…The second is channel coding, which provides good quality and robust transmission. In addition, historical speeds have been reached with the appearance of the two previous technologies combination to give a new system, which is the main basis for the radio-mobile communication system LTE and which allows better exploitation of the higher spectral efficiency with less transmission error [26]- [29].…”

“…LTE uses many advanced technologies, including orthogonal frequency division multiplexing (OFDM) [34]- [37]. Besides these technologies on the uplink (Uplink), it uses single carrier frequency division multiple access (SC-FDMA), while on the downlink (Downlink) [38]- [40], it uses orthogonal frequency division multiple access (OFDMA) [13], [18], [24]- [29]. In this section, we will model the different blocks of the physical layer in the downlink (link between an e-NodeB and a UE) case through examples of the downlink transport channels (DLSCH) [41]- [44].…”
