Over the past several years, orthogonal frequency division multiplexing (OFDM) has received considerable attention from the general wireless community and in particular from the wireless LAN (WLAN) ...

Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...

The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

As designers begin turning to orthogonal frequency division multiplexing (OFDM) in system architectures, they will quickly realize that implementing this modulation scheme is not an easy task.

OFDM is a multi-carrier system where data bits are encoded to multiple sub-carriers, while being sent simultaneously. This results in the optimal usage of bandwidth. A set of orthogonal sub-carriers ...

In last month’s column I described the principles behind OFDM, how it is generated and received and different parameters that can be adjusted to optimize the transmission for different uses. This ...
