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 signaland a signalby 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 signaland the signal, 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.

UWB pulse sequence generation apparatus and method, and data communication apparatus and method using the UWB pulse sequence

A UWB receiver having at least one communication module with a limited working band whose on/off state can be controlled. The UWB receiver is adapted to detect power intensity of a received radio signal in the limited working band based on an on/off state of said at least one communication module. The UWB receiver is adapted to control the on/off state of the at least one communication module based on a result of the detection.

UWB transceiving apparatus and method for dynamically reducing interference

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.
