Question

How to graph the following situation:

Answer 1

I am working on a project and I need to display to my professor the following data involved with communication theory. I did an experiment varying distance(1/2/3/4 feet), delay amount between transmission, and block length (the length of the messages transmitted, ex. 1/2/4/8/16 bytes) and I calculated the bit error rate and byte error rate. What do you guys think would be the best way to display this information?

Clarification: So, for further clarification, the experiment goes something like this. I set up the receiver and transmitter one foot away from each other. Then I transmit a block of data, each a single byte, with 1 millisecond delay between each block. Then 2nd experiment is same one byte transmission with 2 ms delay. And i go up to 4 ms delay. Then, I transmit a new block, with each block being 2 bytes, and i restart from 1 millisecond delay between each BLOCK (not byte). Then I work my way up to 4 ms delay again. Now I repeat this for a block length of 1 byte, 2, 4, 8, 16. So that's a total of 20 experiments. Then, i increase the distance to 2 feet, and i repeat this whole process. Then I increase to 3 feet, then to 4. This is the experiment. Please let me know if I need to give more clarification.

So i have 3 independent variables. Delay amount, block length, distance. I want to see the dependencies between these 3 variables (as suggested by my professor) to gain channel characteristics.

The dependent variable is the bit error rate and the byte error rate.

Answer 2

@ganeshie8 hey Ganesh, this isn't for a specific class, I'm working on a project and I need to present this information to my professor and I was wondering if you could help me.

Answer 3

My initial plan was to have 4 categories. One for each distance. Each distance has 20 tests inside them.

Answer 4

I was told, on Stackoverflow, to use 3D plots but I'm not quite sure how to do that.

Answer 5

So your variables are
1) distance
2) delay between transmission
3) block size

Answer 6

i was thinking of just modeling the delay and block length to show the affect on BER/BLER. And yes, you are right.

Answer 7

You could also give him 3 graphs in xy plane

Answer 8

OO! How so?

Answer 9

In each graph, keep two variables fixed and vary only one variable

Answer 10

Oh that requires 4*3 = 12 graphs i guess

Answer 11

lets tag few others

Answer 14

Well, either way it'd be more wouldn't it? Let's say we're looking at all the experiments with 1 foot separation. So for a block length of 1, I'm testing 4 different delays. Then i'm testing with block length of 2, 4, 8, and 16. So that's 20 tests. but let's say I keep the delay constant, that still gives me 20 tests for each delay.

Answer 15

And If I keep the block length constant, then i have 16 tests but 5 categories. The ideal situation would be just to model the whole thing altogether if there was a way in advanced math.

Answer 16

Keep block size fixed at 1 byte.

Plot BER versus delay for various values of distance. You get four curves :
