  • Method of signal transmission to multiple users from a multi-element array
    Patent number: 7317764
    Abstract: A communication method is provided, in which a data vector u which contains respective signal data destined for each of a plurality of users is transmitted from multiple antennas or other transmitting elements. Prior to transmission, a perturbation vector ?l is added to the data vector u, in which ? is a positive real number and each component of the vector l is a complex number whose real and imaginary parts are both integers. This perturbation is beneficial for improving the total rate of data transmission.
