摘要： Provided are a channel time allocation method and apparatus adopting the same. The channel time allocation method includes: (a) receiving a request of registering in a network from a device; (b) determining whether the network supplying a service required by the device exists; and (c) if the network supplying the requested service exists, performing a procedure of registering in the network, and if the network supplying the requested service does not exist, generating a new network. Since existing MAC protocols can be used in the channel time allocation method, an optimum service is provided in a network environment in which different kinds of services coexist.

摘要： 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.

摘要： Provided is a wireless data transmitting/receiving apparatus and method using an UltraWide Band (UWB). The apparatus includes a random number generator; a random-interval pulse sequence generator; a template pulse sequence generator which generates a reference template pulse sequence used to detect the start point of the random-interval pulse sequence and generates pulse sequences for a signal 0 and a signal 1 by changing the widths of pulses; a random number sequence detector which receives the random-interval pulse sequence and detects information regarding the start point of a random number sequence, using the reference template pulse sequence; and a comparator which compares the pulse sequences for the signal 0 and the signal 1, and determines whether the value of the received random-interval pulse sequence is 0 or 1. Accordingly, it is possible to easily detect information regarding the start point of a pulse sequence while maintaining a processing gain.
