On the Achievable Secrecy Throughput of Block Fading Channels with No Channel State Information at Transmitter [PDF]
2007 41st Annual Conference on Information Sciences and Systems, 2007 We study the block fading wire-tap channel, where a transmitter sends confidential messages to a legitimate receiver over a block fading channel in the presence of an eavesdropper, which listens to the transmission through another independent block fading channel.
