We study a class of three-receiver discrete memoryless broadcast channel (DM-BC) with three degraded message sets and side information. We derive achievable rate region for this three-receive DM-BC with side information noncausally available at the transmitter. When the receivers follow a degradedness order, we determine the perfect secrecy capacity region of this class of three-receiver DM-BC with three degraded message sets and side information noncausally available at both the transmitter and the receiver. The achievable secrecy region of this paper subsumes Steinberg’s rate region for two-receiver degraded BC with the side information and the secrecy capacity region for one-receiver two-eavesdropper DM-BC with no side information as its special cases.

Theoretical Results

Abstract Analyzing wireless communication performances by using information-theoretic results is of practical importance. In this paper, first, an achievable secrecy rate region and an outer bound on the secrecy capacity region for the discrete alphabet and memoryless wiretap channel with side information non-causally known at the transmitter are obtained. Then, by extending the results to the continuous alphabet wireless wiretap channel and by deriving a closed-form expression on the secrecy coverage region (SCR), as a remarkable wireless performance factor, impact of side information on the SCR is analyzed and it is shown that side information increases the SCR as expected intuitively. Numerical evaluation of theoretical results is done finally.
