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 providing a modulated signal useable in a signal transmission system, the method comprising:
establishing an original data frame having a first dimension of at least N elements and a second dimension of at least N elements, wherein N is greater than one; transforming the original data frame in accordance with a time-frequency transformation so as to provide a transformed data matrix wherein the time-frequency transformation is performed using a time-frequency shifting matrix wherein the time-frequency shifting matrix is of a first dimension having N elements and of a second dimension having N elements, where N is greater than one; and generating the modulated signal in accordance with elements of the transformed data matrix. |
