7.2 PHY

The ATWILC1000-MR110xB module WLAN PHY is designed to achieve the reliable and power-efficient physical layer communication specified by IEEE 802.11 b/g/n in single-stream mode with 20 MHz bandwidth. The advanced algorithms are used to achieve maximum throughput in a real-world communication environment with impairments and interference. The PHY implements all the required functions, such as Fast Fourier Transform (FFT), filtering, Forward Error Correction (FEC) that is a Viterbi decoder, frequency, timing acquisition and tracking, channel estimation and equalization, carrier sensing, clear channel assessment and automatic gain control.
