Hey all,
A friend of mine has this little programming problem to solve. Let me
see if i can phrase it correctly.
We have a given number of bits X = 2^B
what would be a simple method to iden...Re: OFDM cyclic extension related question
Col Brown - 2005-02-14 08:48:00
Vikram,
There are a couple of solutions to your problem. The first solution
(to ensure your timing is correct) is to repeat the first OFDM symbol
twice. This ensures that when you take the FFT ...tried sci.maths - no luck, what function am I?
Col Brown - 2005-01-27 09:57:00
All, I have tried posting this to sci.maths, but it seems very high on
the SNR over there. I know that this is not really a DSP problem, but
maybe someone here has an idea(s) how to tackle this one...Re: Two questions about OFDM

Col Brown - 2004-08-17 16:50:00
Hi all,
I'm having a couple of annoying problems trying to match/understand
the performance of various noncoherent detectors for MSK, which is a
special case of CPM (continuous phase family).

Hany
That's an interesting way to model the system, but i'll come back to
that.
What I think you're trying to do is this
H*S / H_est = S
where H = channel and H_est is the channel estim...Re: Iterative least-square estimation
