In this paper, we propose a novel scheme to enhance the spectral efficiency and security of simultaneous wireless information and power transfer (SWIPT) systems. Firstly, the scheme employs generalized spatial modulation (GSM) on transmission antennas and partitioned intelligent reflecting surface (IRS), significantly increasing the number of transmission channels. Consequently, our proposed GSM scheme can transmit more information bits compared to traditional GSM. Secondly, we fully exploit the codeword structure of space-time block coding (STBC) by embedding artificial noise (AN) into the STBC signals. By utilizing channel state information, we set coefficients to cancel out the AN at the legitimate receiver, ensuring that only the illegitimate receiver is affected by the AN, thereby guaranteeing the security of the communication. Finally, since the energy harvesting receiver (EHR) cannot eliminate the AN, it can instead collect more energy through the AN. Additionally, we have derived an upper bound expression for the average bit error probability (ABEP) of the proposed scheme. Our research is of particular interest and use to academics in the field of telecommunications, which comprises an essential segment of your journal’s readership. We believe our research findings align with the aims and scope of your esteemed journal, as they outline approaches to improving bit error rate performance, enhancing security, and optimizing energy harvesting. These aspects are crucial for improving communication quality
