Problems solved by technology

In the frequency band from 3GHz to 10GHz of wireless UWB signals, the loss due to the transmission characteristics of the splitter is greater than the loss due to the reflection characteristics
Therefore, it can be seen that it is difficult to transmit wireless UWB signals through RF splitters

Abstract

A wireline ultra wideband (UWB) signal transmission device, and a wireline ultra wideband signal transmission method of transmitting an ultra wideband signal over a pipeline carrying a cable television (CATV) broadcasting signal. The pipeline includes a plurality of coaxial cables operatively connected through a plurality of splitters that divide the CATV broadcasting signal at a predetermined rate. A plurality of wireline UWB signal transmission devices respectively connected to the pipeline transmit a wireline single band orthogonal frequency division multiplexing (SB-OFDM) based UWB signal through the pipeline and recover a multimedia signal from the SB-OFDM based signal.

Description

[0001] This application claims priority from Korean Patent Application No. 2005-42084 filed with the Korean Intellectual Property Office on May 19, 2005, which is hereby incorporated by reference in its entirety. technical field [0002] Aspects of the present invention relate to a system and method for transmitting an ultra-wideband signal through a pipeline provided in a residence in order to receive a cable television (CATV) signal. More specifically, aspects of the present invention relate to such a wired ultra-wideband signal transmission system and a wired ultra-wideband signal transmission method. Pipes to transmit single-band ultra-wideband (UWB) signals for home networking. Background technique [0003] With the increase of interest in home networks and the development of home network technologies, various technologies for realizing wired / wireless home networks in houses have been proposed. [0004] For example, US Pub...
