In [2], [3], opportunistic secrecy was introduced, which allows channel variations due to fading in order to achieve secrecy, even when the
eavesdropper has a higher average signal-to-noise ratio (SNR).
The achievable ergodic rate for macrocell base station (MBS) users, small-cell base station (SBS) users, and
eavesdroppers of K-tier massive MIMO enabled HetNets are derived respectively on the condition that each MBS transmits artificial noise (AN) in the null space of the main channel to guarantee the secrecy at the intended receiver.
Among the aforementioned works in the area of beamforming for PLS purposes, [7] studied beamforming schemes for decode-and-forward (DF), amplify-and-forward (AF), and cooperative jamming where all available relays were adopted, either to retransmit the source signal or to send an artificial noise to confound the
eavesdropper.
However, secrecy capacity is affected by channel conditions between the source and the destination, as well as those between the source and the
eavesdropper.
An
eavesdropper can also measure the photons but would leave a trail.
Instead of protecting the entire image, preventing an
eavesdropper to decode key portions of the image saves energy while still maintaining a desired level of security.
Further, Gaylin discusses the way the structure of the novel implicates readers as
eavesdroppers.
At the same time, Hamlet's remark, 'Soft you, now, / The fair Ophelia' suggests that his soliloquy has been 'unguarded' up to that moment, and that he does not suspect
eavesdroppers.
There, on a false floor hiding electronic jamming devices designed to thwart
eavesdroppers, they took an oath of secrecy, heard a meditation from a senior cardinal and decided whether to take a first vote - or wait until tomorrow
Since Clare Gaen is so liberal with her condemnation she should not really mind if we Welsh called the English a nation of
eavesdroppers, should she?
They thus also share an interest in the ways in which a given cultural practice, such as Gaylin's eavesdropping or Bailin's "art of being ill," allows illusions of private practice in partly public acts, both for characters and for novel-readers such as we, implicated
eavesdroppers (of a sort) that we are
Defense and aerospace company BAE Systems has come up with high-tech wallpaper that prevents
eavesdroppers from tapping into Wi-Fi networks, but lets other radio signals and mobile phone traffic through.
Faris was told to refer to the cutters as "gas stations" so
eavesdroppers would not get wind of the plot and that he should obtain tools, referred to as "mechanics' shops" that could be used to derail trains.
A COMEDY for one person and 50
eavesdroppers is how Coventry performer Richard Talbot describes new show The Singing Nun.
In a pharmacy at Glen Square, 24-year-old Dora Dunn leaned over the counter and peered into the parking lot, as if to check for
eavesdroppers before she spoke.
