Title:
BROADBAND WIRELESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/074832
Kind Code:
A3
Abstract:
The present invention relates to a broadband wireless system which has a dynamic range of operation of high bit resolution and which can measure and use characteristics of a signal such as an arrival time, intensity, frequency, pulse width and modulation type of the signal, which has a simple configuration and high reliability, and which can use processed signals with ease. The broadband wireless system according to the present invention receives and processes a broadband wireless signal, and comprises: an antenna for receiving the broadband wireless signal; a receiving unit which receives the broadband wireless signal from the antenna, and processes and converts the received signal into a first intermediate frequency signal; a signal distributing unit which converts the first intermediate frequency signal into a plurality of second intermediate frequency signals which are the same as the first frequency signal, and distributes the second intermediate frequency signals; a parallel amplifying unit which amplifies each of the second intermediate frequency signals provided from the signal distributing unit, into respective third intermediate frequency signals in accordance with respective amplifying rates different from each other; a parallel analog-digital converting unit which performs an analog-digital conversion onto each of the third intermediate frequency signals provided from the parallel amplifying unit to generate discrete intermediate frequency signals; and an execution system which analyzes each of the discrete intermediate frequency signals provided from the analog-digital converting unit, selects any one from among the discrete intermediate frequency signals, and processes the selected discrete intermediate frequency signal.
