Error Model for Radio Transmission of MB-OFDM Based Wireless Personal Area Networks (WPANs)

Kurzbeschreibung

The underdeveloping IEEE802.15.3a standard for WPAN is supposed to be able to offer a wireless data link up to 480Mbit/s in a relatively short range. This will bring a significant improvement on the system performance and the support for multimedia applications comparing with the ancient Bluetooth and WLAN systems. To achieve such a high data rate, a UWB spectrum band from 3.1GHz to 10.6GHz has been regulated by FCC for the so called Ultra-Wideband transmission system. Any system can make use of this band, as far as it is a FCC-compliant UWB system, which has a fractional bandwidth greater than 0.2 or a bandwidth greater than 500MHz and power spectrum density always less than 75nW/MHz (-41.3dBm/MHz) between 3.1GHz and 10.6GHz.

One of the most potential PHY proposals for WPANs is the MultiBand-OFDM (MB-OFDM) system, which is based on the traditional OFDM technique that is also used in IEEE802.11a and HiperLAN/2 systems, but running at the UWB spectrum band according to the FCC regulation. The MB-OFDM system can provide a data link ranging from 55Mbit/s@10meters to 480Mbit/s@2meters, as well as up to 18 channels over the entire UWB frequency band.

Inhalt

As our research is targeted at the MAC layer of the MB-OFDM based system, but our MAC layer simulator WARP2 is designed for the IEEE802.11a and HiperLAN2 systems whose PHY layers are slightly different from the MB-OFDM systems, an updated error model for radio transmission of the MB-OFDM system is required for the future research.

The goals of this student project are to:

• understand the IEEE802.11a and MB-OFDM physical layer;
• get familiar with the error model currently used in WARP2 simulator;
• derive a updated error model for MB-OFDM system;

Tools used in our research work:

• matlab
• C/C++
• Specification and Description Language (SDL)
• Unix
• LaTex
• English (fluent)
• Knowledge on mobile communications and wireless channel model will be appreciated

If you have any interest in our research or just want more information, please write me an email or drop by my office at anytime :)
