PHY Modeling

Physical layer options, parameterization, and waveform generation

WLAN Toolbox™ provides functions for modeling 802.11™ physical layer processing. Format configuration objects are used to parameterize these functions and to create WLAN waveforms compliant with IEEE® 802.11 standards.
