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 ...

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 ...

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 ...

All wireless communications systems use some form of modulation to convert a baseband waveform, such as voice or data, to an analog signal that can be carried over the airwaves. The most frequently ...

Over the past year I’ve been writing about potential transmission standards for a nextgeneration broadcast platform (NGBP). The most promising standards are all based on orthogonal frequency division ...

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 ...

As we continue to deploy more DOCSIS 3.1 (D3.1) modems, it is a great time to evaluate if you are getting optimal capacity out of your D3.1 orthogonal frequency division multiplexing (OFDM) downstream ...

The basic idea of multicarrier modulation is to divide the transmitted bitstream into many different substreams and send these over many different subchannels. Typically the subchannels are orthogonal ...
