Radio free-free emission observed by NoRH was combined with multiple line-of-sight EUV observations from STEREO and SDO, which enabled more accurate estimations of the coronal parameters than have ever previously been derived.
From them, we found that the common property of the delay profile was composed of dominant multiple line of sight (LOS) links and a less number of non-LOS delay taps.
From the derived channel delay profiles, we can observe that the common property of the delay profile was composed of dominant multiple line of sight (LOS) links and a less number of non-LOS (NLOS) delay taps.
For example, in a complex mobile wireless channel with significant amount of fading due to reflection and scattering via multiple paths, obstructed line-of-sight, etc., 0's might be transmitted correctly, whereas 1's might be incorrectly received as 0's by a moving car (Additional file 1: Figure S1b).
Indeed, it has multiple lines of authority.
Multiple paths and non-line-of-sight of signal propagation can be the cause of the bias, because they make the signal travel longer distance than the signal that passes through the direct path[11].
After reviewing the hardware development, this chapter further discusses signal processing techniques for hybrid arrays, with focus on angle-of-arrival estimation, single-user line-of-sight multiple-input multiple-output and its capacity, and spatial division multiple access techniques.
We investigate the optimal design of uniform rectangular arrays (URAs) employed in multiple-input multiple-output communications, where a strong line-of-sight (LOS) component is present.
A single master is configured with multiple repeaters to provide a RF line-of-sight telemetry backbone network.
In this article, multiple receiver effects in a non-line-of-sight (NLOS) ultraviolet (UV) communication system is studied.
