So, in practice, the rotation symbol mapper can be implemented through a look-up table that is calculated and stored in advance for a given modulation order and code rate, which is the same as the conventional symbol mapper.

Rotation symbols indicate the views relative to Figure 3B.
Constellation rotation does not increase the complexity, because the rotated symbol mapping can be implemented through look-up table operations as the same as the conventional modulation without rotation.
One possibility is that some participants detected the 'c' within the rotated symbol and were able to use it as a cue, despite the rotation, thereby reducing the observed difference between the two symbols.
Symbols with the highest amplitude will undergo a higher phase rotation than symbols closer to the constellation centre.
The α-OFDM scheme is easily implementable as it only requires an additional time symbol rotation after the IDFT stage and a subsequent phase rotation of the cyclic prefix.
This leads to ISI from symbols in the same subchannel and ICI from symbols in neighboring subchannels at earlier and later time-instants (the neighboring symbols located at the same timing instant have the same phase rotation as the symbol under study, so they do not contribute to ICI, if only CFO is present).
Symbol rotation is performed at the transmitter and at the receiver side in order to account for the delay D required to yield a causal transceiver.
The test consists of five sections: reasoning, letter checking, number distance, odd one out, and symbol rotation.
In point-to-point communication, the carrier frequency mismatch causes signal-to-noise ratio (SNR) loss, a phase rotation of the symbols and intercarrier interference (ICI).
The diagonal matrix that holds the phase rotation that affects each symbol sample is (7).
