how do I generate 100000 bits of ones and zeros with norm distribution mean=5 and standard deviation of 3? I have tried thismu = 5; sigm= 3; x2 = -20:0.1:20; y2 = normrnd(10

I'm trying to generate 100000 bits for ones and 100000 bit for zeros . basically 5 should represent by 1 and -5 by a zero. This is what i have tried

sigma=3, mean=5
x=-20:0.1:20;
y=normpdf(100000, mu sigma)
plot(x,y)

I have tried the zero(100000,-20,20)

the plot plot are looks likethe normal distribution

The y axis range from 0 to 4000 in increments of 500

It's not clear for me what you are trying to do.

I need to compute the bit error rate of a channel where zero has a mean -5 and sigma of 3 and one has mean of 5 and sigma of 3. the probability of one is 50%. compute the bit error rate using simulation of10000 ones and 10000 zeros. plot the pdf. Do it analytically using normcdf,erf or erfc.

Hi gerald,

It appears to me that you are trying to generate 100000 bits of ones and zeros with a norm distribution mean of 5 and standard deviation of 3. Here is an example code for achieving the same:

% Parameters

num_ones = 100000; % Number of ones

num_zeros = 100000; % Number of zeros

mean_one = 5; % Mean for one

mean_zero = -5; % Mean for zero

sigma = 3; % Standard deviation for both zero and one

% Generate random bits for ones and zeros

ones = (rand(1, num_ones) < 0.5) * (mean_one - mean_zero) + mean_zero;

zeros = (rand(1, num_zeros) < 0.5) * (mean_one - mean_zero) + mean_zero;

% Plot the PDF

x = -20:0.1:20; % Range of x values for PDF

pdf_one = normpdf(x, mean_one, sigma);

pdf_zero = normpdf(x, mean_zero, sigma);

figure;

hold on;

plot(x, pdf_one, 'r', 'LineWidth', 2);

plot(x, pdf_zero, 'b', 'LineWidth', 2);

xlabel('Symbol Value');

ylabel('Probability Density');

title('PDF of Zero and One Symbols');

legend('One', 'Zero');

grid on;

Best Regards,

Abhishek Chakram
