Currently I am working on Ultra wideband communication. Specifically I am looking for Multi-user detection ,Multi access, Cross layer optimization and Synchronization issues.

Few things about UWB

• It is a base band technique.
• Frequency band for UWB is 3.1 GHz to 10.6 GHz. , with bandwidth of 10.6 Ghz.
• PSD < -41.3 dBm/MHz.
• If entire band is used then PSD is approximately 0.5 mWatts.
• Proposed Bit rate is hundreds of Mbps to Several Gbps.
• Distance for communication is 1 to 10 mt.  After 20mt or more data rate is very low then existing wireless local area network.
• UWB differs from the Spread Spectrum from its carrierless nature.
• UWB advantages:

•  Low Complexity and low cost ( as it is base band)
•  Noise like signal so resistance to multipath and jamming.
•  Good time domain resolution allowing to use for positionning application
•  Do not required local oscillator at receiver.
