Figure 4 shows these pilot configurations for the mentioned cases.
Depending on the channel characteristics (low/high frequency-dispersive channel, low/high Doppler channel or low/high frequency selective channel), there are different pilot configurations to equalize each subcarrier in OFDM based systems [11].

The auxiliary pilot scheme introduced in Section 3.3.1 can directly be applied to the AMC23 pilot configuration.
The pilot configuration is comb-type (i.e., a given sub-carrier is dedicated to pilots ∀n), the correlation induced between pilots is such that pn,k = pn + 2, k + 210, the pilots are BPSK symbols.
Computer simulations were carried out for several pilot symbol configurations.
The resulting pilot symbol configuration is suited for estimating any number of DCT coefficients not exceeding.
We propose a pilot symbol configuration allowing to estimate any number of DCT coefficients not exceeding the number of pilot symbols, providing a considerable performance improvement as compared to other pilot symbol configurations.
Moreover, we propose a pilot signal configuration, which enables us to estimate a channel impulse response whose order is greater than the guard interval (GI).
A new hybrid pilot plant configuration based on a modularized rolled pipe system (RPS) combined with a submerged flat sheet membrane bioreactor (MBR) was investigated to enhance the sewage treatment and membrane performance.
To unveil some of the refined features associated with internals-containing bubble columns, use was made in this work of two-fluid Euler continuum transient 3-D simulations to simulate five pilot-scale configurations: vessels of uniform filling (dense and sparse), vessels of non-uniform filling with large core and wall clearances, and equal cross-sectional hollow vessels.
