Sentence examples for rail channel from inspiring English sources

Note that prior knowledge about high-speed rail channel characteristics has not carefully been exploited for fast channel estimation yet.

However, as indicated by the high-speed rail channel coherent time (shown in Figure 1), with the increase of train speed and carrier frequency, the radio channel characteristics varies more rapidly and significantly along the high-speed rail line.

Sanding the rail channel and door will ensure no-stick closure.

With the partially drilled hole facing inward slide the door into the rail channels, making sure the door smoothly slides up and down.

The existing high-speed rail line to the Channel tunnel is running some way below capacity, and Hodge said that towns on that route, such as Ebbsfleet, illustrated that additional planning and intervention were needed.

Considering the repetitive movement of a high-speed train along a given high-speed rail line, the radio channel characteristics could be predictable (to some extent) based on the location of high-speed train, local terrain information from a GIS database and past experience.

Britain's first full high-speed rail line, from London to the channel tunnel, was completed in 2007.

By retrieving the dedicated REM for high-speed rail, fast channel awareness can be obtained.

For the high-speed rail radio channel, we assume that these parameters are time-invariant in the duration of an OFDM symbol, and Ф n  = 0.

First of all, we redefine the symbols to be used in this section: N p is the number of detectable paths in the high-speed rail radio channel, and α n, Δf n, p n are the fading amplitude, Doppler frequency shift, and discrete time delay in the n th path, respectively (0 ≤ n ≤ N p – 1).
