e side information contains the information of the phase sequence
that should be applied in order to recover the original signal. Hence,
the phase sequence is derived from the side information. Finally, the
FFT output signal should be divided to the phase sequence vector to
regenerate the input signal.
To verify the performance of the received signal, the BER metric
should be measured.
As shown in Figure4.44, the receiver of the OPS-DSI is almost
similar to the DSI-SLM scheme. e difference is in the side
