Embodiment Construction

[0036] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0037] 1A to 1C illustrate the structure of a data frame used in a chaotic communication system according to an exemplary embodiment of the present invention. When the first piconet and the second piconet exist, the template unit of each data frame is divided into two sections, the first section is allocated to the first piconet, and the second section is allocated to the second piconet.

[0038] Referring to Fig. 1A, the template bit of the first piconet is included in the first section of the template bit frame of the data frame of the first piconet, at least the data bit is included in the first section of each data bit frame of the data unit of the data frame in a paragraph.

[0039] Referring to Fig. 1 B, the template bit of the second piconet is arranged in the second segment of the template bit frame of the data frame of the seco...

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...
