The rigorous definition of ECC involves a **correlation** of vector patterns of your antenna. The equation I think you are using in **matlab** is an approximation. That approximation is particularly bad for low efficiency antennas. I most suspect this is what is causing the discrepancy.

The "Code for Gender Recognition using Auto-**correlation** in **matlab**" was fantastic and worked perfectly for my older version of **matlab**. But once I updated to **matlab** 2015b, the code no longer worked.
Does anyone have a version of this code that works with **matlab** 2015b?

This is another code that I have written for gender recognition in **matlab**. I have attached the files.

Can you elaborate the auto**correlation** part? What the logic?

Is it needed to convert a set of path loss values in dB to linear units like watts before they are correlated to each others in **matlab**.
For example the following gives different results:
x=rand(1,200);
y=rand(1,200);
xx=corr2(x,y)
yy=corr2((10.^(x./10)),(10.^(y./10))) % From dB to linear and then correlated
Thanks

ok, but the question was not yet properly answered :
What do you want compare ?
( Magnitude, bandwidth, **correlation**, etc... )

Dear all,
I am was not convinced or may be could not understand the **correlation** in **matlab** i.e. xcorr function.
So to test I simple made two exactly similar sine wave without any delay, and it gives me delay of 21.
I cannot understand why. please first see the code below
fo=200; fs=2500;
t=0:1/fs:.008;
x=sin(2*pi*fo*t);
y=x; %n

You will need an auto **correlation** filter in both directions, ignoring amplitude and phase. This can "manually" be done with an FFT and a shape comparison in the frequency domain, which is most appropriate for hardware implementation.

How to compare two signals using **correlation** in **matlab**. i know the function is xcorr. But xcorr returns an array of coefficients. What I want to learn is the next step in comparing them. I have no idea of how to compare them.

Hi guys.
I'm working on Voice Conversation project. Briefly, I have two trained data belongs two different people. With a Codec I'm trying to analyise trained data.
Now,I've trouble with this problem.
i.e X= is person K, and Y= is person L. X and Y are 2D matrices.
With the canoncorr function of **matlab** I want to a relation between two matri

Plz help me. I used **correlation** based method to estimate delay for GPS signal but it doesn't show correct result. I think it is because of multipath effect.

Being a fresher for DSP. Take this piece of advice. You type xcorr in **matlab** you ll know as how to code it, rather if you type "**correlation**" in wiki , you ll understand what **correlation** exactly is. With some effort it is possible to know it by your own. Learn a few stuffs , try something and let us know your difficulty we ll help for sure.

Hi
I wanted to know whether the voltage mode controller designed simple boost converter using its small signal model (in sisotool **matlab**) should work in the simulink model of boost converter( which is differential equation model) for all ranges shown stable in the open loop bode plot of compensated system.
