% zREADME.m % Instructions regarding how to run MATLAB experiments in this directory % (UnderstandingLTEwithMATLAB_Chapter5\SISO) % % This folder contains two main MATLAB scripts (testbenches) that showcase how % to execute the SISO transceiver model and look at various signals and how to assess % the qualitative and quantitative performance of the Downlink SISO Mode 1 system % as presented in chapter 5 of the "Understanding LTE withMATLAB" % The main testbenches are called commlteSISO.m & commlteSISO_test_timing_ber.m % % How to run the 1st demo: % type commlteSISO at the MATLAB command prompt % You will see that the script first sets relevant experiment parameters found in MATLAB script % commlteSISO_params.m. It then initializes three LTE transceiver parameter structures % by calling the function commlteSISO_initialize.m. Then it sets up a while loop to call % the main transceiver function commlteSISO_step.m. % Each iteration of the while loop processes one subframe of data. % You will see that after processing each subframe, the script calls the zVisualize.m function to % examine the magnitude spectra of the tranmitted and received signals (before and after equalization) % as well as the modulation constellation of the transmitted and the received signals. % Exploration: % By changing the parametrers found in commlteSISO_params.m you can experiment with various conditions. % For example by chaging parameters such as maxNumErrs and maxNumBits, % you get longer or shorter experiment time. By changing the parameter modType % you can see the effect of using different modulation schemes and by % chaging link SNR, the parameter snrdB, you can se the efect of AWGN noise % on the overall performance. % % How to run the 2nd demo: % type commlteSISO_test_timing_ber at the MATLAB command prompt % You will see that the script first sets relevant experiment parameters found in MATLAB script % commlteSISO_params.m. It then initializes three LTE transceiver parameter structures % by calling the function commlteSISO_initialize.m. Then it iterates % through a set of link SNR values and computes a quantitative performance % measure of BER as a function of SNR. For better results, the experiments % have to be long enough, which usually means parametrers in file % commlteSISO_params.m, known as maxNumErrs and maxNumBits, need to be larger than % 1e4 and 1e7 respectively. % Exploration: % By changing the parameter modType you can see the effect of using different modulation schemes. % By changing the parameters Eqmode and chEstOn , you can experiment with different types of equalizer used % and chanel estimation methods applied, respectively, etc.
