Hi All

I am trying to do a simulation for iterative water-filling algorithm involving two users communicating across a flat-fading channel of four subbands. To calculate for the rate in each sub-bands using shannon limit, i need to get the cross coupling between the two users.

The cross coupling between the two users is a function of the channel matrix of the four sub-bands and SNR gap. I need someone to tell me the values i can assume for channel matrix and SNR gap.

Thanks, in anticipation of an early response.
