GONZALEZ, Giselle; PRADO, Danaisy; MARANTE, Francisco  e  LEDESMA, Arielys. Analysis of LTE and LTE-Advanced system features through simulation processes. Ingeniare. Rev. chil. ing. [online]. 2017, vol.25, n.3, pp.364-375. ISSN 0718-3305.  http://dx.doi.org/10.4067/S0718-33052017000300364.

Nowadays' ongoing development of mobile communications, promoted by the dramatically risen in traffic demand, impulses the deployment of networks with higher throughputs and lower latencies. In this paper, a comparison is made between LTE and LTE-Advanced systems by conducting a study about the parameters, wich at a link level influence the most the data rate experienced by the user. To do so, the LTE and LTE-Advanced Downlink Link Level Simulators developed by the Universidad Tecnológica de Vienna are employed to analyze the communication link between a single user and its Base Station. The results obtained allow to appreciate LTE-Advanced advantages when compared to LTE, given by the usage of superior transmitting modes. Thus, the capacity of MIMO techniques to exploit the intrinsic characteristics of the transmission channel is emphasized.

Palavras-chave : LTE; Throughput; MIMO; base station; user equipment; sub frame; radio channel.
