| Abstract: | In order to realize the anti-eavesdropping ability and increase the system capacity of the multiple input multiple output (MIMO) system, a space hopping pattern generation algorithm of multi-armed bandit based on time reversal (TR-MAB) is proposed. This algorithm considers the error of the channel state information, and based on the time reversal and space hopping communication, the optimal space hopping pattern is selectedly using the multi-armed bandit algorithm to increase the system capacity while reducing the impact of anti-eavesdropping on the performance of legitimate receivers. Theoretical analysis and simulation results show that the algorithm has advantages in anti-eavesdropping performance and system capacity. |
