Hi,
We know that if we use four quadrant arctangent function i.e. ATAN2(Q,I) where we have wrapped phase with discontinuities of 2*PI. There are algorithms which can unwrap this phase. But there are some situations where we have to use two quadrant arctangent function i.e. ATAN(Q/I) where we...
can any one please upload the companion m-files of the following book:
Introduction to Random Signals and Applied Kalman Filtering: with MATLAB Excercises and Solutions by Robert Grover Brown , Patrick Y. C. Hwang
Thanks

Hi,
Can anyone help me in understanding this topic? I know how the code range mesurement is performed but what about the carrier phase measurements?
Thanx
Hi,
Can anybody explain for me why 1st order PLL has smaller transient duration than 2nd order loop for the same value of loop noise equivalent bandwidth??
This is the model I am trying to simulate in matlab . Here F(Z) is is a digital filter.
What I mean by first order loop is F(Z) = A i.e...
This is the model I am trying to simulate. Here F(Z) is is a digital filter.
What I mean by first order loop is F(Z) = A i.e. any constant(obtained from loop bandwidth)
and
for 2nd order loop F(Z) = (aZ-b)/(Z-1). a and b also obtained from loop bandwidth and damping ratio.
Added after 2...
Thanx for explanation. But what I am comparing (by simulating in Matlab)is a 2nd order loop with damping ratio of 0.707 and an input of step function for both 1st order and 2nd order loop.

Do you mean that at sending end first I should encode the data then before transmitting convert it to bits then add the noise and at receiver end received bits should be recoded again and then I should run the decoding algorithms ????????
Will it work ??? I mean to say is it a valid pragmatic...
Hi,
I am currently working on the above mentioned module and I am experiencing a lot of difficulties in designing my own system on this board. Can any one has any experience of working on this module ?? Any application notes or implemented examples ??
Hi,
I am trying to simulate reed solomon codes on awgn channel . I can not understand how I should add the noise in my encoded signal because the signal is in GF(2 ^m) and if I limit the noise in the corresponding field then it will change the variance of the noise. Can any one guide me ...
