The following two MATLAB functions show you can easily implement

the LTE modulation and demodulation algorithms, with all their specifications, using System

objects of the Communications System Toolbox

The Modulator function has two input arguments: the input bit stream (u) and a parameter

representing the modulation mode (Mode). As its output, the function computes the modulated

symbols. The function implements the three different types of modulator used in the LTE

standard. For example, in the case of QPSK, we use a comm.PSKModulator System object

and set its modulation order to 4. Similarly, in the case of 16QAM and 64QAM we use the

comm.RectangulatQAMModulator System objects and set their modulation orders to 16 and

64, respectively. Depending on the value of the modulation mode, we process the input bits to

generate the modulated symbols as the output.-The following two MATLAB functions show how you can easily implement
