摘要

The integration of Multiple-Input Multiple-Output (MIMO) technique by Orthogonal Frequency Division Multiplexing (OFDM) stands out as a robust air interface for upcoming generations of high data and wireless communication. However, this approach faces a challenge in the form of high Peak to Average Power Ratio (PAPR) when stages of symbols in OFDM subcarriers align in way, which builds substantial signal peak in time domain. To address this issue, a novel approach of hybrid Selective Mapping by Partial Transmit Sequence (SLM-PTS) based on the Artificial Bee Colony Optimization (ABCO) algorithm is proposed in MIMO-OFDM. The proposed hybrid SLM-PTS by ABCO approach demonstrates significant PAPR reduction by lower computational complexity, as demonstrated by simulation results. The performance of various versions of SLM-PTS is further analyzed through metrics such as Complementary Cumulative Distribution Function (CCDF), Bit Error Rate (BER), and Symbol Error Rate (SER).
