Antenna combination exploration and performance analysis of GSSK modulation

This paper creatively proposes a new Generalized Space Shift Keying (GSSK) mapping rule that can transmit different antenna numbers at the same time. The antenna combination and performance of GSSK are explored and compared. The transmitting end introduces the transmission principle and antenna combination rules of GSSK. The receiver uses the maximum likelihood algorithm to ensure that the antenna number can be correctly detected. The error problem of the antenna detection and demodulation link is clearly demonstrated. The performance of GSSK with different combinations is simulated and compared. Finally, the performance of GSSK combination is summarized.
