MODULATION AND EQUALIZATION IN AN ORTHONORMAL TIME-FREQUENCY SHIFTING COMMUNICATIONS SYSTEM

摘要

A method for modulating data for transmission within a communication system. The method includes establishing a time-frequency shifting matrix of dimension N×N, wherein N is greater than one. The method further includes combining the time-frequency shifting matrix with a data frame to provide an intermediate data frame. A transformed data matrix is provided by permuting elements of the intermediate data frame. A modulated signal is generated in accordance with elements of the transformed data matrix.

1. A method of data modulation, comprising:
arranging a set of data elements into an original data frame having a first dimension of N elements and a second dimension of M elements, where N and M are greater than one; transforming the original data frame to form a transformed data matrix wherein each element of the transformed data matrix includes a contribution from each of the elements of the original data frame; and generating a modulated signal based upon elements of the transformed data matrix.
