Abstract
Embodiments of the present invention can be used to generate a family of core training sequences having desired cross-correlation and out-of-phase auto-correlation properties for a communications system. The family can be generated by selecting seed sequences, so that the worst-case cross-correlation of the seed sequences is below a first initial threshold and the worst-case out-of-phase auto-correlation of the seed sequences is below a second initial threshold. Then, sequence families can be generated by inserting additional symbols into a corresponding seed sequence. Then, reduced sequence families can be generated by eliminating those sequences from the sequence families that have a worst-case out-of-phase auto-correlation above a third threshold. A sequence is selected from each reduced sequence family, so that the worst-case cross-correlation of the selected sequences is below a fourth threshold.
