They discovered that a sequence of pilot errors had caused a high-altitude stall that led to the deaths of all 228 people on board.
This ambiguity is resolved using a sequence of pilot symbols, considerably shorter than needed in training-based techniques.

A source transmits to the destination a frame consisting of a sequence of Kp pilot symbols cp and a sequence of K data symbols c; the latter is obtained by applying Kb information bits b to a trellis encoder [5].
By transmitting a sequence of known pilot tones, and observing the received sequence over a given time interval, our specific interest lies in developing and investigating the properties of the joint ML estimator of the CFO μ0, STO τ0 and CIR h[l] for the generic OFDM/OQAM transceiver system illustrated in Fig. 1 and described in mathematical terms in Section 2.1.
During the downlink training phase, the BS simultaneously transmits a sequence of N training pilot symbols to all users.
In a realistic scenario, the channel transfer function for the downlink has to be measured applying for example pilot assisted channel estimation (PACE) in a time division duplex (TDD) system, i.e., in the uplink each MSs transmits a sequence of M P pilot symbols d p = [ d p, 1, …, d p, M P ] T with d p H d p = M P which are known to the BS.
In [25], a method is proposed for a comb-type configuration of the pilots where assuming a finite sequence of pilots.
The pair of I/ Qmodulated channel coefficients h++ and h+− at each subcarrier index can be estimated either separately or jointly, using a known sequence of pilots.
Time domain methods, e.g., [24 26], attempt to estimate the channel impulse response (CIR) by using sequences of pilot tones.
For uncorrelated channels, a closed form expression is derived for the optimal pilot sequence, number of pilot subcarriers and pilot locations.
And when the show does get at something deeper, bolder — or has a musical scene as stirring as the final sequence of the pilot?

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
