An indirect impedance measurement approach that does not require direct cable attachment or large space using a two-port network is presented. Using a straight wire monopole as an interrogating antenn...
Closed Form Secrecy Capacity of MIMO Wiretap Channels with Two Transmit Antennas
Secrecy capacity MIMO wiretap channel physical layer security
2011/9/22
Abstract: A Gaussian multiple-input multiple-output (MIMO) wiretap channel model is considered. The input is a two-antenna transmitter, while the outputs are the legitimate receiver and an eavesdroppe...
Achieving "Massive MIMO" Spectral Efficiency with a Not-so-Large Number of Antennas
