Li, Meng; Derudder, Veerle; Desset, Claude; Dewilde, Andy; Bourdoux, André; Huang, Yanxiang

802.11ay is the amendment to the 802.11 standard that enables Wi- Fi devices to achieve 100 Gbps using the unlicensed mm-Wave (60 GHz) band at comparable ranges to todays commercial 60 GHz devices based on the 802.11ad standard.
The target throughput in 802.11ay single stream is 44 Gbps for 256- QAM, while 176 Gbps for MIMO 4 streams.
The QC LDPC codes for 802.11ay is derived from 802.11ad by lifting. There are two code length 672, 1344, each has 5 different rates.
The goal of the work is to design a standard compliant LDPC decoder for 802.11ay with high throughput, high energy and area efficiency.
