“…In [12], the authors compared the performances of an LTE-A uplink system in flat Rayleigh and pedestrian channels by Least Square (LS) and Adaptive Linear Minimum Mean Square Error (ALMMSE). In addition, they compared the performance of an LTE-A system in terms of BER and throughput related to SNR.…”

This paper evaluates the effects of high mobility of Users Equipment (UEs) on the performances of different data rate services using four scheduling algorithms in the uplink of LTE system using the uplink Vienna simulator.The uplink reports Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI) and Rank Indicator (RI) to inform the evolved node base station (eNodeB or eNB) about the current channel state. We simulate 20 and 30 UEs switch at high mobility and different service demands. Simulation results show that under 100 kmh-1 speed the Best CQI and Proportional Fair schedulers are the best in performance for low delay and the Round Robin algorithm is the worst scheduling algorithm among other schedulers.
