IEEE 802.11ad (WiGig) – LDPC Decoder Applications

IEEE 802.11ad is an amendment to IEEE 802.11-2007. Its intention is to modify the physical and MAC layer of the standard to enable a high throughput data transmission in the 60 GHz frequency band.

The standard defines four LDPC codes that are different from the codes defined in IEEE 802.11n and IEEE 802.11ac. LDPC coding is mandatory, no other coding scheme is specified. The increased submatrix size (42) of the parity check matrices relaxes the problem of achieving Gbit throughputs for such small block lengths in comparison to IEEE 802.11ac/n. In those standards the submatrix size is only 27 for a block length of 648 bits.
