If you change the paramter rfade from 0 to 1, you can include the effect of fading.īy changing the value of Eb/N0 (variable ebn0), you can obtain the graph that shows the relationship between Eb/N0 and BER and that can been seen in the figures of the book.Dallas/Fort Worth Area CEO, Senior Marine Scientist, Editor Environmental Services Education Duke University Nicholas School of the Environment 2002 - 2004 Master of Environmental Management, Coastal Environmental Management Lyon College 1998 - 2002 B.S, Biology Experience Azura Consulting LLC April 2014 - Present American Journal Experts April 2013 - Present Aquatic Mammals Journal 2012 - Present Geo-Marine Inc.
And, simulation result is stored in the file (BER.dat) defined with (1)-(y). Where first number 3 is Eb/No, second number 4492 is the number of errors, third number 200000 is the number of data, and fourth number 2.246000e-002 is BER. (3) Then, you can see the following simulation result on your command window. (y) Output file name to store the simulation results (w) Flat fading or not (0-Normal, 1-Flat)
(o) Do you include the Rayleigh fading or not ? (0-No, 1-Yes)
#KAISER PHYSIOTOOLS CODE#
(i) Code sequence (1-M-sequence, 2-Gold sequence, 3-Orthogonal Gold sequecne) Īnd, the function goldseq(m1,m2,N) outputs N one-chip shifted Gold-sequences.įirst of all, we set simulation parameters in "dscdma.m". The function mseq(X,Y,Z) outputs an M-sequence of the stage number X, the position of feedback taps Y, and the initial value of registers Z.Īnd, the function mseq(X,Y,Z,N) outputs N one-chip shifted M-sequences.įirst of all, you must prepare preferred pair of M-sequences.įor example, you type the following commands, and generate M-sequences m1, m2.Īs a result, you can get a Gold-sequence. > crosscorr(,)Īs a result, the following cross-correlation value is obtained. If you would like to calculate of sequences and, you can type the following command. If you would like to calculate of a sequence, you can type the following commandĪs a result, the following auto-correlation value is obtained. If you copy all of files to /matlabR12/work/chapter5, you only type the following command. Next, you can go to the directory that have all of programs in this section by using change directory (cd) command. Then, you start to run MATLAB and you can see the following command prompt in the command window. If you would like to try to use the above programs by using MATLAB.įirst of all, please copy all of files to your created adequate directory. The relationship between file name and the number of program written in the book is shown in as follows. In this directory, we can find the seventeen files. % to We try to do our best to answer your questions. % If you have any bugs and questions in our simulation programs, please e-mail
