WebThe channel then appears to the encoder and decoder as a time-invariant AWGN channel. This power adaptation is called channel inversion. Fading channel capacity with channel inversion is just the capacity of an AWGN channel with constant SNR ˙ C = B log 2[1 + ˙] What is the advantage and disadvantage of this scheme?. Webrate a channel can support. • Capacity is a channel characteristic - not dependent on transmission or reception tech-niques or limitation. • In AWGN, C = Blog2(1+γ) bps, where B is the signal bandwdith and γ = P/(N0B) is the received signal-to-noise power ratio. 2.
