N2 - Covert communication is mainly achieved via concealing or masking the legitimate transmissions from being passively detected by the hostile nodes. In this research, we introduce and investigate a covert communication proposal with the assistance of a friendly jammer. In our proposal, jamming based interference injection and channel uncertainty are both employed for enhancing the covertness of legitimate communication. Based on the formulated detecting model, the average minimum detection error probability is derived for the hostile monitoring node. We deduce the outage probability and the covert throughput achievable by the legitimate receiving node. In addition, we detail a two-phase based bisection algorithm for attaining the maximal covert throughput with joint optimal of jamming power and transmission information rate. Finally, simulation results reveal the effectiveness of the proposed covert wireless system.
