Abstract :
We consider the fast Rayleigh fading wiretap channel, over which a legitimate transmitter wishes to have secure communication with a legitimate receiver in the presence of an eavesdropper. We consider an average power constraint on the input, and assume that no channel state information (CSI) is available to any user. We show that the input distribution that achieves the secrecy capacity for this wiretap channel is discrete with a finite number of mass points.
