Abstract


This paper deals with Matlab simulation of Long Term Evolution system (Lte) to show data rate of the uplink layer from user equipment toward the tower with respect to the size of Desecrate Fourier Transform process (DFT) which will be increased from 2 to the size of Inverse Desecrate Fourier Transform process (IDFT). Also it shows the way of using Cyclic Prefix technique (CP) in Lte system and its types which effect on the data rate for uplink layer. Finally the results will show the value of Lte system data rate for different types of modulation and Cyclic Prefix which will be for many types of system bandwidth individually, and it will show the minimum and maximum values of (DFT) process size with the midpoint which is the best one.
