Shannon meets Stackelberg on the cognitive interference channel part I: A deterministic view

Abstract

In this paper, we have combined a game-theoretic and an information-theoretic notions to describe the selfish behavior of each user in a two-user linear deterministic cognitive interference channel (LD-CIC). The two-user LD-CIC is the simple case of the cognitive radio technology in the high SNR regime. This model is a solution to improve the spectral efficiency in software defined network (SDN) concept in 5G. In the two-user LD-CIC, the information bits of the primary/licensed transmitter is a-priori provided at the cognitive/secondary/unlicensed transmitter. So that, the cognitive transmitter can cooperate and utilize the frequency spectrum to send the information bits of the both transmitters. In information-theoretic approaches, full cooperation is assumed between transmitters for codebook and rate selection in this channel.
