This study investigates multi‐layer coding over a dirty‐paper channel. First, it is demonstrated that superposition coding in such channel still achieves the capacity of interference‐free additive white Gaussian noise channel when the transmitter is non‐causally aware of interference signal. Then, the problem is extended to the dirty‐paper block fading channel, where it is shown that in the lack of channel information at the transmitter, the so‐called broadcast approach maximises the average achievable rate of such channel.
