On The Three-Receiver Multilevel Broadcast Channel with Random Parameters

In this paper we extend the analysis of tworeceiver broadcast channels with random parameters to the three-receivers case. Specifically we base our work on Nair and El Gamal's results for the three-receiver discrete memoryless multilevel broadcast channel and assume that state information is available non-causally at the transmitter.We provide an achievable rate region for this setting and acknowledge its importance in the study of multiuser cognitive radio configurations.
