  • Non-uniform beam spatial modulation method and system applicable to multi-antenna communication and sensing integration
    Patent number: 12191967
    Abstract: A non-uniform beam spatial modulation method and system applicable to multi-antenna communication and sensing integration; the method includes: finding an ISAC beam that satisfies both sensing performance and communication performance, including: constructing a communication transmitting signal; constructing a communication receiving signal; constructing an upper bound of the integrated communication and sensing spectral efficiency of the non-uniform beam spatial modulation; constructing an objective function of the sensing performance; and finding a candidate beam matrix and a beam activation probability distribution where the spectrum frequency is maximum and the sensing performance is best; and finding a spectral efficiency of non-uniform beam spatial modulation by means of the ISAC beam. Under the condition of meeting the same sensing performance requirement, the spectral efficiency of the present invention is higher.
