< Back Tuesday, May 27, 2008 Time: 12 - 1 Location: 4004/4006 (4th floor Atkinson) The physical layer of WiMedia OFDM UWB Rabih Chrabieh The WiMedia Ultra-Wideband system uses OFDM, rather than ultra-narrow impulses, to fill up a vast amount of spectrum, more than 500 MHz, with high data rate transmissions at short distances, and very low power. In a nutshell, it is like a high data rate Bluetooth. We will present the physical layer of this standard with some references to the MAC layer. In particular, we will talk about OFDM and sub-carrier layout, packet detection and synchronization, channel estimation, header and payload structures, coding and modulation, phase noise tracking, piconet and super frame structures, etc. |
