Abstract
The invention relates to the use of the sequences TSn0: 1 0 1 0 0 0 0 1 1 1 1 0 1 0 0 1 1 0 1 0 0 0 0 1 1 1, TSn1: 0 1 1 1 1 1 0 1 0 0 0 0 0 1 0 1 0 1 1 1 1 1 0 1 0 0 as training sequences in cellular mobile radiotelephony, specially GSM (Global System for Mobile Communications). Said training sequences have improved cross-correlation properties.
