These channels correspond to the signals received by 3 transmitting antennas and 4 receiving antennas. To process these raw signals, we first apply the range Fast Fourier Transform (FFT) and angle FFT to each time frame of the signals. This transforms the signals into a 3-dimensional ...
Moreover, in a Rician fading environment where directional beam antennas are assumed to be used to improve the degradation due to severe multipath signals, an overall E_b/N_O improvement at Pe of 10^lt-5gt of 3.0dB is achieved compared to simple differential detection when the condition of ...

PanoRadar is a sensor that operates like a lighthouse that sweeps its beam in a circle to scan the entire horizon. The system consists of a rotating vertical array of antennas that scans its surroundings. As they rotate, these antennas send out radio waves and listen for their reflections fr...
Different from omni-directional antennas that have a uniform gain in each direction, directional an- tennas have a different antenna gain in each direction. As a result the signal level at a receiver can be increased or de- creased simply by rotating the orientation of the directional ...
the wireless communication device transmits the constituent signals on respective antennas for multiple-in-multiple-out (MIMO) based wireless communications. The constituent signals can be separately encoded and modulated. At a receiving device, wireless channel conditions such as noise or fading can inc...

The main part of the time delay in VLBI is the geometric time delay, which is determined by the geometric position of the satellite and the observation station. The time delay of a satellite signal arriving at two antennas can be expressed as: Δτ ¼ ρ1 − c ρ2 ¼ Δρ c ...
