| Summary: | The wired connectivity for the increasing number
of peripheral devices to complement computer functions has
become so large and inconvenient that wireless connectivity has
become a necessity. Wireless connectivity is also necessary for
digital systems in industrial, commercial, medical, military and
domestic applications. A fast digital technique is proposed, based
on Impulse Radio Ultra-Wide Band (IR-UWB) technology. It is
theoretically analysed and practically implemented with excellent
results. The suggested scheme is potentially best short range
UWB wireless technology in terms of speed, capacity, power, cost
and spectral mask, which complies with FCC regulations. It
overcomes interference with all existing narrowband systems
including GPS, PCS, WiMAX, WLAN 802.11b and 802.11a, and
surpasses existing techniques, which have limited interference
mitigation levels or mitigation at the cost of both reduced
performance or increased system complexity.
The proposed UWB pulses are portions of sine waves, which
is a novel application of simple pulse shapes based on half
rectified or mono cycle sine waves in the GHz range. Theoretical
analysis and results obtained by simulation show excellent
consistency with results obtained by experimental measurements.
The technique can be used with more than one user at a time.
Two users can be connected simultaneously each with 1 Gbps.
The spectrum of one is centred at 4.5 GHz and the other is
centered around 9 GHz. One user can operate with 2Gbps. |
