Problems solved by technology

[0006] However, the existing spatial modulation technology still faces many challenges when used in IoV communication. For example, the spectral efficiency of GSSK and GSM is difficult to meet the growing demand for mobile traffic. Although MA-SM has high spectral efficiency, the actual bit error rate is relatively high. , cannot guarantee reliable communication
