Abstract :
We examine communication over block fading additive Gaussian channels with delayed channel state information feedback and finite decoding delay constraints. Following an approach due to Cover (1972), we apply the broadcast strategy and find the maximum achievable expected rate in cases where the underlying parallel Gaussian broadcast channels are not degraded in the same direction
