Figure 20: Channel function code for LTE/LTE A

First, we undergo a fading channel functionality and then we compute to the additive white Gaussian noise and then we add that noise to the receiver.

Test bench function for LTE/LTE A:

Since LTE have numerous parameters We would be designing an example generator which will give us some clear idea of what is going on.

Figure 23: LTE/LTE A Example Generator

We can observe that we have set some different and unique parameters which are capable of giving us some good waveforms defining the LTE parameters and specifications. Here we are setting a eNodeB (Enhanced node B) Parameters or Physical Downlink Shared Channel (PDSCH) the parameters that reflect the MIMO mode which goes through the PDSCH which contains the used data. The first function at eNodeB relates with the transmission bandwidth.

Here we are using LTE/ LTE A Mode Spatial Multiplexing Bandwidth 10 MHz with 4 layers of antennas. We are using a 16 QAM technique with a coding rate of 0.667 with an SNR of 10db we get a very distorted Constellation diagram from a receiver signal. By changing the SNR value between 23 and 27 we get better results in terms of PER and BER. We also get a good data rate of about 60 Mega bits per second.

The shade in yellow represents the transmitted signal and the shade in blue represents the fading channel of the correspondent transmitted signal.
