OFDM for Mobile Data Communications
Orthogonal frequency division multiplexing (OFDM) is a communications technique that divides a communications channel into a number of equally spaced frequency bands.
A subcarrier carrying a portion of the user information is transmitted in each band.
Each subcarrier is orthogonal (independent of each other) with every other subcarrier, differentiating OFDM from the commonly used frequency division multiplexing (FDM).

OFDM Tutorial
Frequency division multiplexing (FDM) is a technology that transmits multiple signals simultaneously over a single transmission path, such as a cable or wireless system.
Each signal travels within its own unique frequency range (carrier), which is modulated by the data (text, voice, video, etc.).

OFDM/OFDMA Audio Visual Tutorial for WiFi and WiMAX
OFDM Tutorial Summary The OFDM Tutorial goes in depth into the theory and implementation of OFDM wireless communication systems.
Starting with the treatment of multipath fading channels, OFDM is introduced as a bandwidth efficient robust communication system for multipath fading channels.
Using IEEE 802.11a as a basis, a full OFDM system is described in both theory and implementation.
In particular, detailed description of acquisition...

OFDM: Old Technology for New Markets
For years, broadcast wireless networking was limited to practical speeds of less than 11Mbps.
Now, with the advent of Orthogonal Frequency Division Multiplexing (OFDM) (define), wireless standards like IEEE 802.11a and 802.11g (define) are moving the real-world wireless LAN speed limit to 50Mbps and beyond.

OFDM Receiver Design
Othogonal Frequency Division Multiplex (OFDM) has gained considerable attention in recent years.
It has been adopted for various standards include the 802.11a wireless LAN standard.
In this project, we implemented an OFDM receiver based 802.11a standard.

Orthogonal Frequency Division Multiplexing (OFDM) Explained
Orthogonal Frequency Division Multiplexing (OFDM) is a wireless technology patented in 1970 that runs on the principle of transmitting data by dividing the data stream into multiple parallel bit streams that have a much lower bit rate and using these sub-streams to modulate several carriers.
Although OFDM has been around since the 1960s, only recently has it been recognized as an outstanding method for high speed, bi-directional wireless...
