% Program 2-8
% bpskev.m
%
% Evaluation program of fading counter based BPSK transmission scheme
% This program is one of example simulations that include fading
% As for the explanation you can check Chapter 3.
%
% Programmed by H.Harada
%
%******************** Preparation part **********************
% Time resolution时间分辨力
% In this case 0.5us is used as an example
tstp = 0.5*1.0e-6;
% Symbol rate符号速率
% In this case we assume that each sample time is equal to 1/(symbol rate).
% In this case 200 kbps is considered.
sr = 1/tstp ;
% Arrival time for each multipath normalized by tstp,延迟时间
% In this simulation four-path Rayleigh fading are considered
itau = [0 2 3 4];
% Mean power for each multipath normalized by direct wave.相对功率分贝衰减值
% In this simulation four-path Rayleigh fading are considered.
% This means that the second path is -10dB less than the first direct path.
dlvl = [0 10 20 25];
% Number of waves to generate fading for each multipath.产生衰落的波形个数
% In this simulation four-path Rayleigh fading are considered.
% In normal case more than six waves are needed to generate Rayleigh fading
n0=[6767];
% Initial Phase of delayed wave,初始相位角度
% In this simulation four-path Rayleigh fading are considered.
th1=[0.00.00.00.0];
% Number of fading counter to skip (50us/0.5us),衰落计数器跳数,用于产生各个多径衰落之间的互相独立特性
% In this case we assume to skip 50 us
itnd0=100*2;
% Initial value of fading counter衰落计数器初始值
% In this simulation four-path Rayleigh fading are considered.
% Therefore four fading counter are needed.
itnd1=[10002000 3000 4000];
% Number of directwave + Number of delayed wave
% In this simulation four-path Rayleigh fading are considered
now1=4;
% Maximum Doppler frequency [Hz]
% You can insert your favorite value
fd=200;
% Number of data to simulate one loop
% In this case 100 data are assumed to consider
nd = 100;
% You can decide two mode to simulate fading by changing the variable flat
% flat : flat fading or not
% (1->flat (only amplitude is fluctuated)0->nomal(phase and amplitude are fluctutated)
flat =1;
%******************** START CALCULATION *********************
nloop = 1000; % Number of simulation loop
noe = 0; % Initial number of errors
nod = 0; % Initial number of transmitted data
for iii=1:nloop
%******************** Data generation ***********************
data=rand(1nd)>0.5; % rand: built in function
%******************** BPSK modulation ***********************
data1=data.*2-1; % Change data from 1 or 0 notation to +1 or -1 notation
%********************** Fading channel **********************
% Generated data are fed into a fading simulator
% In the case of BPSK only Ich data are fed into fading counter
[data6data7]=sefade(data1zeros(1length(data1))itaudlvlth1n0itnd1now1length(data1)tstpfdflat);
% Updata fading counter
itnd1 = itnd1+ i
