Why License CommStack's OFDM Modem IP Cores?
White Paper CommStack has developed several OFDM (Orthogonal Frequency Division Multiplexing) modems as synthesizable Hardware Description Language (HDL) cores that are available for license. CommStack's OFDM Modem cores allow its licensees to implement such... [03 Jul 2008]
IEEE 802.11g Explained
White Paper The Intersil proposal requires use of Orthogonal Frequency Division Multiplexing (OFDM) for higher data rates (>20 Mbps) and requires support for Complimentary Code Keying (CCK) to ensure backward compatibility with existing 802.11b radios as... [03 Jul 2008]
802.11 Wireless Chip Set Technology White Paper
White Paper The 802.11g WLAN standard offers many important improvements for wireless LAN users - including the faster data rates and robust orthogonal frequency division multiplexing (OFDM) of 802.11a -- while operating in the same unlicensed ISM frequency... [03 Jul 2008]
Voice Over an OFDM Based Wireless LAN
White Paper This paper addresses the problem of efficiently integrating speech communication devices, such as cordless telephones, with an "Orthogonal Frequency Division Multiplexing" (OFDM) based wireless LAN. It is argued that traditional "voice over IP... [15 Jan 2008]
Wi-fi patent threat looms after US ruling
News Csiro claims its patent covers a core method for transmitting wireless signals that use orthogonal frequency division multiplexing (OFDM) modulation, which breaks signals into different parts to transmit data simultaneously over different... [21 Nov 2006]
Co-Existence of 802.11g WLANs With Bluetooth
White Paper Orthogonal-frequency-division multiplexing (OFDM) based wireless local-area-networks(WLANs) will be implemented in the 2.4 GHz Industrial-Scientific -Medical (ISM) band. The advantages of OFDM WLANs are very high data rates, resilience to multipath... [12 Aug 2005]
802.16: A Future Option for Wireless MANs
White Paper To accommodate non-line-of-site access over lower frequencies, IEEE published 802.16a in January 2003, which includes support for mesh architecture.a operates in the licensed and unlicensed frequencies between 2GHz and 11GHz using orthogonal... [24 Nov 2004]
Sensitivity of OFDM Based WLANs to Front-End Impairments
White Paper Multicarrier systems based on Orthogonal Frequency Division Multiplexing (OFDM) are gaining popularity in high-speed broadband wireless networks such as IEEE 802.11a and IEEE 802.11g Wireless LANs. OFDM based systems have the advantage of... [02 Nov 2004]
IEEE 802.11g New Draft Standard Clarifies Future of Wireless LAN
White Paper The 802.11g draft standard utilizes existing elements from the original complimentary code keying (CCK)-orthogonal frequency division multiplexing (ODFM) and Packet Binary Convolutional Code (PBCC)-22 proposals. [25 Feb 2004]
TI's 'turbo Wi-Fi' - still born?
News In the 802.11g standards battle, PBCC eventually lost ground to OFDM, or Orthogonal Frequency Division Multiplexing, as the modem of choice. Texas Instruments' 'turbo Wi-Fi' technology may be downshifting out of the wireless networking fast lane... [14 Nov 2002]
