摘要：
In this article, covert multi-channel communication against interference-assisted proactive detection is investigated in additive Gaussian white noise (AWGN) channel. We first analyze the detection performance for the warden and derive the covert constraints. Then, to maximize the average effective covert throughput (AECT) of the legitimate communicating parties, we establish an optimization problem by jointly optimizing the sub-channels number and transmit power. Analysis and numerical results show that selecting an appropriate number of sub-channels can improve the AECT against interference-assisted proactive detection comparison with single-channel schemes.
