OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...

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 ...

Virtually all modern wireless standards have adopted orthogonal frequency division multiplexing (OFDM) as their modulation and access method. Wi-Fi 802.11a/g/n uses it. So do the mobile and fixed ...

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 ...
