OFDM uses multiple carriers—some of the newer standards support up to 32,000 carriers per channel—unlike the current VSB modulation. With VSB a single carrier is modulated with data at a high symbol ...

Modulation basics, part 3: Spread spectrum and OFDM June 15, 2008 by Ian Poole, Adrio Communications Ltd, Staines, UK Comments 0 Advertisement ...

MIMO and OFDM Basics A typical MIMO configuration includes a 2×2 system with two transmitters and two receivers. A 4×4 system has four transmitters and four receivers, and so forth. MIMO transmitters ...

Creating and Analyzing OFDM Signals One of the early steps in a design flow for a custom OFDM SDR application is to create and analyze the custom or proprietary signals in simulation to design the ...

Optical transmission systems with terabit per second (Tbit s−1) single-channel line rates no longer seem to be too far-fetched. New services such as cloud computing, three-dimensional high ...

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 ...
