This paper considers the classic non-causal state information problem in channel coding where non-causal channel state knowledge at the transmitter, which is also called the Gel'fand Pinsker problem. This paper determines Lagrangian dual expression for this problem, illustrating that Costa's dirty paper coding result can be replicated using the dual-problem methodology.
