Abstract
A communication device for generating a matrix-mapped sequence is described. The communication device includes sequence generation circuitry. The communication device also includes mapping circuitry coupled to the sequence generation circuitry. The mapping circuitry applies a first matrix with at least one column multiplied by −1 to a sequence. The communication device also includes a transmit block coupled to the mapping circuitry.
