A recent breakthrough in wireless communications, multiple-input multiple-output (MIMO) technique, vastly expands the capacity and range of communications.
In wireless communications, multiple-input multiple-output (MIMO) systems provide substantial benefits in both increasing system capacity and improving its immunity to deep fading in the channel [1, 2].
R-dimensional (R-D) harmonic retrieval (HR) in colored noise, where R≥2, is required in numerous applications including radar, sonar, mobile communications, multiple-input multiple-output channel estimation and nuclear magnetic resonance spectroscopy.
For multi-sensor network communications, a multiple event-triggered mechanism is employed firstly, which can reduce communication burden of each channel.
The civil rights groups also opposed similar efforts in later years to allow law enforcement to get a single court order to trace suspect telephone or computer communications across multiple networks or phone companies.
"There's a conflicting message that comes out from the Republicans if we want to recognize the unifying power of English, and meanwhile, we send out communications in multiple languages," Representative Steve King, Republican of Iowa, told National Journal.
