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

摘要

A system and method of providing a modulated signal useable in a signal transmission system. The method includes transforming, perhaps with respect to both time and frequency, a data frame including a plurality of data elements into a transformed data matrix. The transformed data matrix includes a plurality of transformed data elements where each of the plurality of transformed data elements is based upon each of the plurality of data elements. The method further includes generating the modulated signal in accordance with the transformed data elements of the transformed data matrix.

1. A method, comprising:
transforming a data frame including a plurality of data elements into a transformed data matrix having a plurality of transformed data elements wherein ones of the plurality of transformed data elements are based upon multiple ones of the plurality of data elements and wherein the transformed data matrix has a first dimension of N transformed data elements and a second dimension of M transformed data elements, wherein N and M are greater than one; generating a modulated signal in accordance with the transformed data elements of the transformed data matrix; and transmitting, from at least one antenna of a wireless device, the modulated signal using a carrier signal.
