TR35 Jaiganesh Balakrishnan Final TR35 Jaiganesh Balakrishnan Final Presentation Transcript

  • Jaiganesh Balakrishnan (Texas Instruments) Multi-band OFDM Ultra Wide Band (UWB) Communication System for High Speed Wireless Personal Area Networks (WPAN).
  • Multi-band OFDM UWB System (1)
    • In 2002, FCC opened up the spectrum from 3.1 – 10.6 GHz to allow low power UWB devices.
    • Opportunity for high data rate communication (> 100 Mbps) over short distances (up to 10 meters) for WPAN applications.
    • Challenges: (1) World-wide regulatory compliance (2) Wide-band processing (3) Low cost solution (4) Low transmit power (5) Multi-path performance and (6) Co-existence
    • The multi-band OFDM technology addressed the challenges faced by UWB devices and shifted focus away from traditional impulse radio systems.
    • Multi-banding and OFDM provided spectral flexibility enabling world-wide regulatory compliance.
    • Time Frequency Coding addressed the issue of wide-band processing while simultaneously enhancing performance.
    • Innovative signal structure using OFDM, enabled excellent multi-path performance, albeit at a low implementation complexity.
    Multi-band OFDM UWB System (2)
    • The Multi-band OFDM system has been standardized by the WiMedia Alliance, approved by ECMA International and published as the ECMA-368 standard.
    • A number of products incorporating the Multi-band OFDM UWB technology have started hitting the market.
      • Wireless USB
      • Wireless HDMI
    • Evinced keen interest in the academic community leading to numerous research publications.
