Method and apparatus for ultra wideband communications system employing a spread spectrum technique transmitting a baseband signal over a wide frequency band

摘要

A transmitter for ultra wideband communications includes a spread modulator for spreading input data to a wideband signal having a form in which a plurality of carriers are constantly transmitted and a amplifier for amplifying the spread signal obtained from the spread modulator. The amplified signal obtained from the amplifier is transmitted as a baseband signal by one of a wired and wireless transmission.
