Consider a point-to-point channel as in Figure 2.2 and suppose the coded modulation rate is R (see Section 2.2.3). Let 7 be the average SNR at the receiver and let I(7) be the mutual information between the channel inputs and outputs. Observe that I(7) is a random variable that depends on the fading coefficients. We […]
We study the performance of cooperative protocols for the network shown in Figure 5.2. The network outputs are for i = 1,2,… ,n. The transmitting nodes have half-duplex constraints. The noise variables Zu,i, u = 1,2,3, i = 1,2,…,n, and channel gains Huv are the usual complex, Gaussian random variables (see Section 3.2 and (3.3a) […]
