Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


We start with a direct transmission link as depicted in Figure 2.1(a) and assume the channel model incorporating path-loss and Rayleigh fading. The received signal at the destination d is modeled as yd[n] = as, dxs[n] + nd[n], (2.1) where xs[n] is the signal transmitted by a source s, n ∈ [1, …, N ] is the index of the transmitting packet, and nd[n] is additive white Gaussian noise, with variance σ2 n, at the receiver. The channel gain as, d between the nodes s and d is modeled as as, d = hs, d/dα/2 s, d, where ds, d is the distance between the nodes s and d, α is the path-loss exponent, and hs, d captures the channel fading characteristics. The channel fading parameter hs, d is assumed to be complex Gaussian with zero mean and unit variance, and independent and identically distributed (i.i.d.) across times slots, packets, and links.
