  • Orthogonal precoding for sidelobe suppression
    Patent number: 11095490
    Abstract: A transmitter of a DFT-based communications system including an orthogonal precoder for transforming modulated data symbols using a unitary transform, wherein the data 5 symbols are mapped to subcarriers of the transmitter and the computational complexity of the transform is linear with respect to the number of the subcarriers.
    Type: Grant

  • Low complexity multi-channel modulation method and apparatus
    Patent number: 7876838
    Abstract: A digital communications apparatus for processing a data vector includes a transmitter for communicating with a receiver across a channel having channel characteristics. A transmit vector is computed from the data vector and from values defining a basis for a transmit lattice. The transmit lattice defines a set of transmit symbols of length N and is related to an orthogonal receive lattice by the channel characteristics. The computation is performed according to an algorithm of order N complexity.
