The most promising standards are all based on orthogonal frequency division multiplexing (OFDM), specifically “Coded” OFDM (COFDM). This month I’ll take a closer look at the basic technology behind ...

ISI results when the bit rate of a channel is large compared with the delay spread. OFDM works by multiplexing the high-frequency content onto many orthogonal carrier signals that can be broadcast at ...

At first the network neutrality issue for broadband Internet service was all about the desire of carriers to realize value from content that customers wanted to download. Spokespeople for carriers ...
