Abstract :
The security gap of a wireless network composed of two legitimate nodes and one eavesdropper, all provided with multiple antennas, is evaluated. The use of transmit antenna selection combined with frame scrambling may lead to gaps <;0 dB, under feasible scrambling depths and a practical number of transmit antennas is shown.
