% zREADME.m % Instructions regarding how to run MATLAB experiments in this directory % (UnderstandingLTEwithMATLAB_Chapter4) % % This folder contains a series of MATLAB scripts (testbenches) that showcase % modulation, scrambling and coding functionalities used in the LTE standard % for DLSCH and PDSCH as presented in chapter 4 of the "Understanding LTE with % MATLAB" % Testbenches performing experiments 1 to 6 depend on calling main functions % chap4_ex01.m, chap4_ex02.m all the way to chap6_ex06.m. % % How to run the demos: % 1. To perform experiment 1 and 2, use the BERTOOL of the Communications % System Toolbox. % type bertool at the MATLAB command prompt. Go to Monte Carlo tab, choose % either chap4_ex01.m or chap4_ex02.m in the "Simulation MATLAB file ..." edit % box, set a range of EbNo values, set the BER variable name to ber, and % set typical values for parameters Number of errors & Number of bits. % For better results, the experiments have to be long enough, % which usually means parametrers Number of errors or Number of bits % need to be larger than 1e4 and 1e7 respectively. % Exploration: % By successively commenting and uncommenting lines 5-7 % in MATLAB files chap4_ex01.m or chap4_ex02.m, % you effectively choose a different modulation mode of either QPSK, QAM16 and QAM***. % Repeat the above process after changing the modulation mode. % % 2. To perform the 3rd experiment, you can run the following testbenches: % a) chap4_ex03_performanceBER.m % Compares BER performance of turbo coders as a function of number of % decoding iterations % b) chap4_ex03_performanceProfiling.m % Profiles the transceiver system model and identifies which component takes the most time % c) chap4_ex03_performanceTiming.m % Computates simulation time for system transceivers that include turbo coders % as a function of number of iterations % % 3. To perform the 4th experiment, you can run the following testbenches: % a) chap4_ex04_performanceBER.m % Compares BER performance of system transceivers that include turbo coders % with and without early termination decoding and shows how close the performances are % b) chap4_ex04_performanceTiming.m % Computates simulation time for system transceivers that include turbo coders % with and without early termination decoding. It shows how similar % the performance in early termination case to that of the regular case with much less % computation time. % % 4. To perform the 5th experiment, you can run the following testbench: % chap4_ex05_performanceBER.m % It Compares BER performances of system transceivers including turbo coders % as a function of coding rate (effect of rate matching) % % 5. To perform the 6th experiment, you can run the following testbench: % chap4_ex06_performanceBER.m % The corresponding main function chap4_ex06.m implements a fairly acurate % version of Transport channel processing (in Downlink DLSCH processing) % together with scrambling and modulation mapping operations of PDSCH processing. % When you run the testbench, you compare BER performance of transport block processing % as a function of max. number of iterations.
