cramer rao lower bound on estimator's variance
I am wanted know equation on cramer rao lower bound on estimator
variance(lowest possible limit on variance) for a given SNR, the
number of data point and mathematically expression of the estimator.
Any reference on this topic will also be great....

I am finding the amplitude of the signal using complex demodulation
(quadrature demodulation). I wanted to know maximum accuracy to which
the amplitude of the one of the frequency contained in phase modulated
signal(which is the input) can be estimated.The accuracy to which the
amplitude obtained should be 10^-8 (between actual and estimated by
this method). So i wanted to know if there is any cramer rao bound
(accuracy to which amplitude of the signal can be estimated). The SNR
of the signal is about 55 to 60 dB.

firstname.lastname@example.org...Cramer Rao Bound
I guess this is more of a math question, but I thought someone here
could help me. I'm confused about the different forms of the vector
Cramer Rao Bound. Specifically, let x be the parameter vector, and
let L(x) be the log pdf. Then the Fisher matrix is
Now I understand the second form- it is a full rank matrix. But form
(1) is the product of two vectors- hence, it is rank deficient, and
cannot be inverted to obtain the minimum variance. So how are these
two forms equivalent? Am I reading the math wrong? Thanks!

...Cramer Rao Bound and GFSK frequency errors
I know this has been covered extensively in the past but with your
indulgence I'd like to bring up CRLBs again.
My problem is this: I've implemeted a method of measuring ( or rather
estimating ) the carrier frequency errors in GFSK signals from
Bluetooth radios. From many tests on RF IC ATE I have data for the
variance of my measurements. Intuitively it seemed sensible that there
should be a way of relating the SNR of the captured signal I extract
the frequency error from and the measurement variance due to that SNR.
Knowing this I can make an objective judgement about the effica...Help with computing the Crame Rao Lower Bound for Time Delay Estimation
I am trying to retrieve the theoretical value of the time delay estimate when using a chirp signal.
According to theory (see http://www.ws.binghamton.edu/fowler/fowler%20personal%20page/EE522_files/EECE%20522%20Notes_08%20Ch_3%20CRLB%20Examples%20in%20Book.pdf slide 4/19), the Cramer Rao Lower Bound should be given by:
This is the theoretical lower bound for the variance of any unbiased estimator of the time delay.

Check out ...Wideband DOA estimation

First, the mentioned methods are based on the narrow-band signal model.
It is not obvious how to extend such methods to the wideband situation...MUSIC and DOA Estimation
In the literature, there is a common claim made that the performance
of MUSIC for direction of arrival estimation (DOA) is affected when
the wrong number of directional sources is assumed. There is no
argument presented to support this claim, nor any references given,
just the claim.
I am curious what the basis for this claim is. Although there are a
variety of MUSIC-like methods and a this topic can get complicated,
overall, it seems pretty fair to say that when you underestimate the
number of sources, it is due to the presence of sources whose signals
are weak (relative to the noise fl...cramer using matlab

For example, I can fit experiment data by normal distbution as the
following. However, I want to estimate the confidence interval, too.
How could I acheive this purpose (shown in figure with confidence
bound) from fitting information such as stdfit, WSSR and others?

since you can't expect people to do your work your request will not
likely get an answer.
