% zREADME.m % Instructions regarding how to run MATLAB experiments in this directory % (UnderstandingLTEwithMATLAB_Chapter3) % % This folder contains a series of MATLAB functions that showcase % modulation, scrambling and coding functionalities used in the LTE standard % for DLSCH and PDSCH as presented in chapter 3 of the "Understanding LTE with % MATLAB" % % How to run the demos: % 1. To perform experiment 1, type chap3_ex01 at the MATLAB command prompt. % Notice how simulated and theoretical BER performaqnce measures are % computed and compared for a simple transceiver composed of a modulator % and demodulator with an AWGN channel. % The experiment shows how to use System objects of % Communications System Toolbox to set up a basic experiment and verify the % results. % % To perform experiments 2 to 5, use the BERTOOL of the Communications % System Toolbox as follows: % type bertool at the MATLAB command prompt. % Go to Monte Carlo tab, % In the "Simulation MATLAB file ..." edit-box choose either of the % following main functions % chap3_ex02_qpsk.m % chap3_ex03_qpsk_viterbi.m % chap3_ex04_qpsk_viterbi_soft.m % chap5_ex05_qpsk_turbo.m % In each case, 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.
