Abstract

A synchronization method and apparatus and a location awareness method and apparatus in a chaotic communication system are provided. The location awareness method includes receiving a data frame which includes a template chaotic signal to be determined to be arranged at a predetermined position of the data frame, and a data source signal obtained by modulating the template chaotic signal, the position allocated to a user; detecting a position of the data frame in which the template chaotic signal is substantially arranged; and determining the distance between a device transmitting the data frame and a device receiving the data frame using the difference between the position of the data frame in which the template chaotic signal is substantially arranged and the predetermined position. Accordingly, it is possible to precisely detect the distance between devices.

Description

technical field

[0001] Apparatuses and methods consistent with the present invention relate to a chaotic communication system, and more particularly, to synchronization and location awareness in a chaotic communication system. Background technique

[0002] Traditional wireless standards require more power consumption and complex communication structures to transmit data at high speeds. However, despite the low data transmission speed, most industrial or home wireless monitoring and control applications require a communication system with longer battery life and less complex structure.

[0003] IEEE 802.15.3a is a standard for ultra-wideband (UWB)-based wireless multimedia communication led by the IEEE 802.15 working group. The IEEE 802.15.3a standard supports data rates up to 54 Mbps, which is still faster than that provided by competing standards such as IEEE 8012.11 or Bluetooth. Therefore, the IEEE802.15.3a standard can be used to transmit digi...
