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 ...

An unusual collaboration of authors produced what is likely the longest NCTA paper ever at The Cable Show 2012, held in Boston back in May. The paper, comprising some 185 pages, was written and ...

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 ...

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation technique in which a high-rate data stream is divided into a number of parallel low-rate substreams, each modulating an ...

OFDM is a special form of multicarrier modulation (MCM), where a single data stream is transmitted over a number of lower rate subcarriers. It is worth mentioning here that OFDM can be seen as either ...

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 ...
