Abstract :
We investigate the achievable secrecy rate with Gaussian random codes when the main channel is an AWGN channel, while the eavesdropper´s channel is Rayleigh fading with additive Gaussian noise. Several transmission strategies according to the main channel´s relative channel gain are proposed and evaluated. We show that even if the main channel channel gain is arbitrarily worse than the eavesdropper´s average channel gain, positive secrecy rate can still be achieved with artificial noise injection and a burst signaling strategy.
