The path losses in two radio links using the same channel are characterized by the following gain matrix:

a) If the maximum transmit power in each of the transmitters is 1 W and the noise power is 10−9 W, what is the largest minimum signal SINR that can be maintained in both receivers simultaneously? b) What happens if the maximum transmit power is 10 W? Infinite?
