TR35 Jaiganesh Balakrishnan Final

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