Patent ID: 8615697

Claim:
A method for implementing Low Density Parity Check (LDPC) codes in an IEEE 802.11 standard system configured to operate in a Multiple-Input, Multiple-Output (MIMO) schema, comprising: a) defining a base LDPC code, having a length equal to an integer number of data carriers in an Orthogonal Frequency Division Multiplexing (OFDM) symbol; b) receiving the base LDPC code on a plurality of sub-carriers, wherein the base LDPC code is transmitted at an expected phase on sub-carriers specified by the IEEE 802.11 standard system, and c) receiving the base LDPC code on sub-carriers other than those specified by the IEEE 802.11 standard system, wherein the base LDPC code on the other sub-carriers is transmitted offset in phase from the base LDPC code on the specified sub-carriers.
