Appl. No.:

13/116976

Inventors:

H. Lee Ward - Albuquerque NM, US

Assignee:

International Classification:

H03M 13/03

US Classification:

714796, 714758, 714777

Abstract:

A plurality of columns for a check matrix that implements a distance d linear error correcting code are populated by providing a set of vectors from which to populate the columns, and applying to the set of vectors a filter operation that reduces the set by eliminating therefrom all vectors that would, if used to populate the columns, prevent the check matrix from satisfying a column-wise linear independence requirement associated with check matrices of distance d linear codes. One of the vectors from the reduced set may then be selected to populate one of the columns. The filtering and selecting repeats iteratively until either all of the columns are populated or the number of currently unpopulated columns exceeds the number of vectors in the reduced set. Columns for the check matrix may be processed to reduce the amount of logic needed to implement the check matrix in circuit logic.

Abstract:

Mobile devices are assigned to their correct base stations after taking into consideration interference from all other mobile devices. The resulting assignments are more efficient than previous assignments. In addition, transmit power levels are assigned after each mobile device is assigned to a base station. The assigned power levels allow for more efficient use of power during the transmission of data signals.
