  In this paper, we propose a polar coding scheme for secure communication over
the multiple-input, single-output, single-antenna eavesdropper (MISOSE) fading
channel. We consider the case of block fading channels with known eavesdropper
channel state information (CSI) and the case of fading channels with known
eavesdropper channel distribution information (CDI). We use the artificial
noise assisted secure precoding method to maximize the secrecy capacity in the
first case, and to overcome the unawareness of the eavesdropper CSI in the
second case. We show that our proposed scheme can provide both reliable and
secure communication over the MISOSE channel with low encoding and decoding
complexity.
