System and Method for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) Offset Quadrature Amplitude Modulation (OQAM)

摘要

In one embodiment, a method for transmitting data in a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM)-offset quadrature amplitude modulation (OQAM) system includes selecting a precoding matrix in accordance with a projection of the precoding matrix on a precoding space and generating a precoded modulated pulse shape by applying the precoding matrix to a data vector and a pulse shape. The method also includes transmitting, by a first device to a second device, the precoded modulated pulse shape.

1. A method for transmitting data in a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM)-offset quadrature amplitude modulation (OQAM) system, the method comprising:
partitioning a time-frequency lattice into blocks; assigning a plurality of pre-coding matrices to the blocks such that a pre-coding matrix is assigned to a block; selecting a subset of columns of the pre-coding matrix to maximize a projection of the pre-coding matrix on a pre-coding space; generating a pre-coded modulated pulse shape by applying the pre-coding matrix to a data vector and a pulse shape; and transmitting, by a first device to a second device, the pre-coded modulated pulse shape.
