implementation of Time division multiple access in matlab

    clc
    clear all;
    close all;
    num_node=input('Enter number of node for network=');
    No_of_time_slots=num_node;
    Bandwidth=200; %Khz
    time_slots_length=input('Enter the length of time slot');%seconds
    Guard_interval=input('Enter the value of guard interval');
    for i=1:1:No_of_time_slots
        pause(time_slots_length);
        a(i)=time_slots_length;
    end
  endclc;

This is the code i have written on my own. I need to know the corrections in it.

Do you see how it is to read your code? See http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup .

All we see is the current code. But how could we suggest corrections, if you do not mention, what is wrong or what you want to change?

I want to implement tdma as i have writtern earlier but this code is not giving me any desirable output.. I have considered suppose 10 nodes so it will consider 10 time slot then i will ask the user to give the time slot length then at the end i want to see how much total time required to transmit data?

@Niharika Pantawane: You ignore that I asked you to format your code properly. It is a very simple procedure: Open your question for editing, mark the code and press the "{} Code" button. If you want others to read your code, it is worth to present it in a readable form.

@Niharika Pantawane: Now your code is readable.

What output is desirable for you? What is the purpose of the pause command? Do you really want the code to wait? I did not work with "Time division multiple access", but you did. To implement this, you have to understand this topic at all, so it would be useful if you explain, what you want to achieve. Then the forum can help you with the implementation.

Thank you for your feedback. That pause is just i have tried bt not getting desirable output. Actually i want to calculate the time required to transmit the packets. For example if i m considering 10nodes so there will b 10 time slots.. At the end i want to calculate the total transmission time .i.e. delay. Since i have to compare its performance with CSMA/CA. How to find the delay?

[Jan]

How is the delay defined? Do you have any formula or definition?

For the implementation in Matlab, the terms "CSMA/CA" and "tdma" are confusing only. Remember, that the most readers of the forum do not work in your field of science. And for the actual code, all we need to know is the formula, which you should know, e.g. from your text book or homework question. You could search in WikiPedia also.

excuseme sir;

can you give me a short brief about your code, please?
