Many applications demand simultaneous localization and aggregation in wireless sensor networks. For such an application, e.g. wildlife monitoring, a signaling scheme for a combined localization and communication using a common set of subcarriers is proposed. The concept is based on binary offset carrier signals. But, in contrast to Global Navigation Satellite Systems the presented approach makes use of pure subcarrier localization, and thus enables data transmission in short burst signals. The ranging performance is assessed utilizing the Cramér-Rao Lower Bound depending on the amount of data transferred and considering bit errors.
