Secure DoF of MIMO Rayleigh block fading wiretap channels with No CSI anywhere
2014
2014 IEEE International Conference on Communications (ICC)
We consider the block Rayleigh fading multipleinput multiple-output (MIMO) wiretap channel with no prior channel state information (CSI) available at any of the terminals. The channel gains remain constant in a coherence time of T symbols, and then change to another independent realization. The transmitter, the legitimate receiver and the eavesdropper have nt, nr and ne antennas, respectively. We determine the exact secure degrees of freedom (s.d.o.f.) of this system when T ≥ 2 min(nt, nr). We
