Abstract :
A secure space-time block coding (STBC) scheme for 2 and 4 transmit antennas is proposed in the presence of a passive eavesdropper. The bit error probability is analyzed for coherent detection as well as with differential detection. The analytical expressions are validated through simulations and demonstrate that our proposed secure STBC guarantees full diversity to an intended recipient while reducing the diversity order of an eavesdropper to zero even when she has perfect channel state information.
