A Gaussian channel with slow fading (Corresp.)

An interleaved fading channel whose state is known to the receiver is analyzed. The reliability functionE(R)is obtained for ratesRin the rangeR_c leq R leq C. The capacity is shown to beC = E_A { frac{1}{2} ln (1 + A^2 n)}whereAis a factor describing the fading mechanism anduis the signal-to-noise ratio per dimension.
