[Tinyos-help] Corr value

[Rodolfo de Paz Alberola]

Hi all,
 
I am emulating cc2420 radio chip in avrora and testing it with
tinyos-2.x. Right now, I am working with LQI and RSSI values. 

However, I don't have idea of how to simulate the correlation value. In
the data sheet says that this value can be seen like a "chip error
rate". So, I was thinking about using the S/N and then the BER to
calculate that, but, I don't understand why it ranges between 50 and
110.

Do you have any idea of how to model that? 

Any suggestion will be really appreciated.
