An additional topic covered by modulation research is the modulation format.

QAM is only a modulation format and does not specify the format of the digital data being carried.

It also features low current consumption and supports flexible data rates and modulation formats.

In optical communications optical fibers allow for transmission distances of more than 100 km without amplification depending on the bit rate and modulation format used for transmission.

On-off keying has been the commonly used modulation format in optical communications.

MT63 has been mooted as a modulation format for Time Signal Stations, but the implied system does not use Vericode.

Simulations permit to evaluate critical parameters, such as modulation formats, launching conditions, and operating temperature for global bandwidth and eye diagram optimization up to 10 Gbit/s.

GSE Packets may be sent in different Base Band frames, not necessarily consecutive or with the same transmission parameters (modulation format, coding rate).

Modeling and simulation of mixed modulation formats for improved CDMA bandwidth efficiency.

This bandwidth is independent of the modulation format, the frequency and the receiver.
