hello,who has done the task of time delay estimation algorithm?can you give me a algorithm?thanks.

can you give me a algorithm

Answer 1

[Adam]

If you have the Signal Processing Toolbox:

doc xcorr
doc alignsignals
doc finddelay

You'll have to do some reading and trying out though, I'm not doing your work for you!

Here the time delay estimation is in process control

[Adam]

Give some proper information in your question. 'can you give me a algorithm' doesn't count as a question to which you are going to get detailed answers!

[hui lu]

The system

A (z ^ (- 1)) y (k) = z ^ (- d) B (z) u (k) + v (k)

Among them,

A (z ^ (- 1)) = 1 - a_1 z ^ (- 1) - ... - a_na z ^ (- na)，
B（z^(-1)）=1-b_1 z^(-1)-…-b_nb z^(-nb)，
-- y : output of the system.
-- u : control action (input to the system).
-- v: noise with non zero mean.
-- d : time delay in the system.

I want to get a algorithm to estimate the time delay (d).

hui lu - you don't get it. Answers is not here to provide code for you. That you want something is not sufficient. That you will write down the mathematical statement of what you want written for you is not sufficient. Your question is not a MATLAB question, it is a doit4me. Adam has given you some ideas as to what you might use. So now it is time for you to make an effort.
