Signal Reception

Functions for 802.11™ physical layer reception processing

WLAN Toolbox™ provides functions that synchronize, demodulate, and decode 802.11 waveforms. Use these functions to detect waveform characteristics, estimate and correct for symbol timing offset, estimate and correct for carrier frequency offset, and estimate the channel. The functions also demodulate and recover individual preamble and data fields.
