Abstract :
In this paper, we investigate secure communications by introducing superimposed pilots for multiple antenna system. The superimposed pilots enable the trellis-based joint channel tracking and data detection for the user of interest. Further, by adjusting the power ratio between the data symbol and superimposed pilot symbol, the secure capacity region can be established. The user of interest can appropriately select the Forward Error Correction (FEC) code rate, to prevent any possible eavesdropping. In this paper, we present the achievable secure capacity region for multiple antenna system, and verify it via Monte Carlo simulation as well.
