<p>Attached is the O3K channel model we discussed yesterday. It
also contains a suggestion for how to state the O3K coding
performance. I welcome your comments. If we can agree to the
model in the next week or so, each agency may be able to begin
simulating with it and discuss some initial results at the May
teleconferences.</p>
<p>A few notes:</p>
<ul>
<li>I am suggesting we study 10 Gsps, 78.125 Msps, and 1.22 Mbps,
since those include the highest and lowest data rates and one in
the middle.</li>
<li>I don't have a good suggestion for the TIA noise density at
1.22 Msps. Dirk, would you be able to supply a number?<br>
</li>
<li>I have algebraically simplified the expressions for the means
and variances. You can compare the model to the expressions
Dariush presented on yesterday (p. 5), and check my algebra.<br>
</li>
<li>I have included the fading parameter as well. Just set rho=1
if you want no fading.</li>
</ul>
