what is the mean of delay?

Dear Sir or Madam,

I would like to know the mean of delay. Can I understand 1 bit delay, if both bit is A=[0 0 1 1 0] and B=[0 1 1 0 0]. I want to know because I can't get expected data when using align signals block and error rate calculation block in simulink. So, I think that align signals block don't work. Maybe I can't understand the mean of delay.

I'm glad if you let me know.

Sincerely,

[Birdman]

Can you share your simulink model?(export to r2017a)

Dear cvklpstunc

Thank you for your reply. This is simulink model.

What is Align Signals block? What does it do? What is within it?

[SHUNSUKE YAMANAKA]

Dear cvklpstunc

Thank you for your reply. I use align signals to align bit shift between Tx and Rx. Shouldn't I do this manipulation?

Sincerely,

[Birdman]

Can you directly share the simulink model with me, the file? (export it to r2017a)

[SHUNSUKE YAMANAKA]

Dear Birdman

Thank you for your reply. This is simulink model.

Sincerely,

[Birdman]

I also need Tx and Rx variables.

[SHUNSUKE YAMANAKA]

Dear Birdman,

Thank you for your reply and I'm sorry to reply to you late. It is Tx and Rx.

Sincerely,

Answer 1

[Birdman]

Well, I think the reason you can not understand those blocks was because you can not supply Tx and Rx to Simulink. You misarranged them. I changed the way they work and now you see some result on Display blocks. Hope this helps. Let me know the results.

When you run the simulation, the mat file is automatically loaded but make sure they are in current directory of yours.

[SHUNSUKE YAMANAKA]

Dear Sir or Madam,

Thank you for your reply. I tried running simulation with your data in simulink. Display data shows '0 0 0'.

[Birdman]

Change the sampling time in From Workspace blocks to 0.05 and please use the mat file that I have sent to you.

It shows values different than '0 0 0'.

Answer 2

[SHUNSUKE YAMANAKA]

Dear Sir or Madam,

Thank you for your reply. It values '0.5759 110 191'. I used your mat file.

Sincerely,

[Birdman]

Is it how you wanted it to be ? Does it solve your problem?

If so, you can accept my answer.

[SHUNSUKE YAMANAKA]

Dear Birdman,

Thank you for your reply. I think that BER should be '0'. Is this system accurate to calculate BER?

Sincerely,

[Birdman]

What is BER?

[SHUNSUKE YAMANAKA]

Dear Birdman,

BER is bit error rate. The conclusion of BER is 0.5759.

Sincerely,

[Birdman]

What about the other two values? What should they be representing?

[SHUNSUKE YAMANAKA]

Dear Birdman, The number of error of bit and the number of bit that are compared.

Sincerely,

[Birdman]

Numerically, what should they be showing?

'0 0 0'? or something else?

[SHUNSUKE YAMANAKA]

Dear Birdman,

It should be ' 0 0 191', I think.

Sincerely,

[SHUNSUKE YAMANAKA]

But, inaccuracy of the data may cause this problem. So, I want to recognize that this simulink system is accurate.

[Birdman]

Well, that's it from me Shunsuke. If you think my answer was helpful, you can accept it. Good luck after this point. :)

[SHUNSUKE YAMANAKA]

Dear Birdman,

Thank you. I can get the BER data that I want to.

Sincerely,

[Birdman]

Accept mine answer, not yours.

[SHUNSUKE YAMANAKA]

Dear Birdman,

I accept your answer.

Sincerely,
