- Abstract
For closed-loop multiple-input multiple-output (MIMO) precoding, the random symbol encryption and the secrecy capacity are analyzed. For receiver with channel and precoding matrix estimation error, an upper bound of eavesdropper signal-interference-noise ratio (SINR) is derived. Simulation results show that the secrecy capacity increases with the increase of the numbers of transmitting and receiving antennas, the eavesdropper couldn't intercepte the information even if it has higher signal - to - noise ratio (SNR). The estimation error will lead to the decrease of eavesdropper SINR,and the influence of the precoding matrix estimation error is even worse.
