Enhanced Polarized Spatial Modulation With Optimal Power Allocation

IEEE Transactions on Wireless Communications
This article introduces binary polarized spatial modulation (BPSM) and permutation-based polarized spatial modulation (PPSM) for multi-input, multi-output systems leveraging polarized antennas. The proposed schemes utilize all available transmit antennas to enhance spectral efficiency (SE) while minimizing inter-antenna correlation.
