Achievable secure degrees of freedom of MISO broadcast channel With alternating CSIT
2014
2014 IEEE International Symposium on Information Theory
We study the problem of secure transmission over a twouser Gaussian multi-input single-output (MISO) broadcast channel under the assumption that the channel to each receiver is conveyed either perfectly (P) or with delay (D) to the transmitter. Denoting S 1 and S 2 to be the channel state information at the transmitter (CSIT) of user 1 and user 2, respectively; the overall CSIT can then alternate between four states, i.e., (S 1 , S 2 ) ∈ {P, D} 2 . We denote λ S 1 S 2 be the fraction of time
