This work presents the concerns of reliable, comprehensive, and high-quality communication networks essential in
wireless communications for Industry 4.0. These are considered critical requirements of wireless technology for Industry
4.0. For a reliable transmission of digital data over broadband widths and Giga Hertz channels, the corresponding Peak-to-
Average-Power Ratio (PAPR) must be under control. Industry standards Multiple-Input Multiple-Output Orthogonal
Frequency Division Multiplexing With Offset Quadrature Amplitude Modulation (MIMO-OFDM/OQAM) system has been
considered as the modulation technique with less Computational Complexity (CC). It usually produces phase sequence sets
with different PAPR, a complex phenomenon to control. For robustness in PAPR control, the technique proposed has a
receiver that initially restores the frequency domain rotation signal according to the sequence selection of the transmitter.
Then it compares the distance between the reverse rotation sequence and the nearest constellation point to restore the
original sequence. The proposed method simulation results can efficiently suppress the PAPR of MIMO-OFDM/OQAM
signals. The proposed method is compared with the traditional Selective Mapping (SLM) algorithm. The proposed method
reduces the CC, and can obtain the approximate Bit-Error Rate (BER) performance of the conventional SLM method when
the sideband side information is known.
