the answer to your question can be had by searching the COMP.DSP
postings previously..please use various keywords related to your
problem and understanding and you will surely find..since i remember
in COMP.DSP 2 sets of topic discussions were there on this and each
went to not less than 10 messages or replies from different authors

Hi, here

I don't understand the definition of the Sampling frequency in
802.16Rev2/D2

It is defined as

Fs = floor(n*BW/8000)*8000    where, n=8/7 is the sampling factor.

Q1: According to the Nyquist Sampling Theorem, the Fs should be larger
than 2 times of BW. But here, Fs is similar to BW. Why?

Q2: What is the usage of the function floor( ) ?

Thanks for your time.
