2. Self-interference cancellation - Wikipedia

   en.wikipedia.org/wiki/Self-interference_cancellation

   Self-interference cancellation ( SIC) is a signal processing technique that enables a radio transceiver to simultaneously transmit and receive on a single channel, a pair of partially-overlapping channels, or any pair of channels in the same frequency band. When used to allow simultaneous transmission and reception on the same frequency ...

3. Noise temperature (antenna) - Wikipedia

   en.wikipedia.org/wiki/Noise_temperature_(antenna)

   Noise temperature (antenna) In radio frequency (RF) applications such as radio, radar and telecommunications, noise temperature of an antenna is a measure of the noise power density contributed by the antenna to the overall RF receiver system. It is defined as "the temperature of a resistor having an available thermal noise power per unit ...

4. Antenna (radio) - Wikipedia

   en.wikipedia.org/wiki/Antenna_(radio)

   Antenna (radio) In radio engineering, an antenna ( American English) or aerial ( British English) is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. [1] In transmission, a radio transmitter supplies an electric current to the antenna's terminals ...

5. Omnidirectional antenna - Wikipedia

   en.wikipedia.org/wiki/Omnidirectional_antenna

   Whip antenna on a walkie-talkie. In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis ( azimuthal directions), with power varying with angle to the axis ( elevation angle ), declining to zero on the axis. [1] [2] When graphed in three dimensions (see ...

6. Noise-canceling microphone - Wikipedia

   en.wikipedia.org/wiki/Noise-canceling_microphone

   The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio. Applications. Call center headsets

7. Radiation pattern - Wikipedia

   en.wikipedia.org/wiki/Radiation_pattern

   Therefore, in discussions of radiation patterns the antenna can be viewed as either transmitting or receiving, whichever is more convenient. This applies only to the passive antenna elements; active antennas that include amplifiers or other components are no longer reciprocal devices. Typical patterns Typical polar radiation plot.
