A multi‐agent reinforcement learning anti‐jamming method with partially overlapping channels

open access: yesIET Communications, 2021
This paper investigates the problem of multi‐user anti‐jamming channel access with partially overlapping channels (POC). Compared with traditional anti‐jamming systems that use non‐overlapping channels, POC improve the spectral efficiency.
