Summary:In order to increase the efficiency of spectrum usage, MIMO-OFDM and OFDM are commonly utilized in wireless systems and high-data-rate communications. It is difficult to lower the Peak-to-Average Power Ratio (PAPR) with MIMO-OFDM. This study has proposed a new approach for PAPR reduction in MIMO-OFDM called Adaptive Tunicate Swarm Optimization with Partial Transmit Sequence (ATSO-PTS). For encoding and decoding in MIMO-OFDM, this study utilizes the No square-matrix-based Differential Space Time Coding (NDSTC) scheme. MIMO-OFDM is a type of linear error-correcting code utilized for transmission over noisy channels. For modulation and demodulation, this study employs pre-specified Quadrature Phase Shift Keying (QPSK) symbols. On the receiving end, it has executed Fast Fourier Transform (FFT) and serial to parallel (S/P) conversion, after which it has demodulated to extract the output bits. With performance measures like PAPR, BER, and SNR values of roughly 2.9,0.01, and 0.025, respectively, the proposed ATSO-PTS method outperforms other approaches like TSHO-PTS, SLM-PTS, and PS-GWPTS.
