Computer Network (QAM Format)

Follow the steps below: 1. Install MATLAB and make sure to include the LTE Toolbox. 2. Follow the instructions shown in the following webpage: [login to view URL] [login to view URL] to create a BER cure for the Physical Downlink Shared Channel (PDSCH) of an LTE network. Here, you need only to change the SNR range to be from -3 to 20 dB. a. Show the BER curves when you are varying the modulation and coding scheme (MSC) from: QPSK, 16-QAM, 64-QAM, to 256-QAM b. Discuss the obtained plots and explain in details your findings. You need to mention the impact of the chosen MCS on the BER, and how receivers have to adaptively adjust their MSC to ensure an acceptable BER range. I have done 1 and 2(a) as shown in attachment , I need help for 2(b)
