Claim:
A multiple-input multiple-output (MIMO) transmitter, comprising: a scrambler configured to receive user data, and generate scrambled data in response to the user data; and a forward error correction encoder configured to generate, based on the scrambled data, encoded data using a low density parity check (LDPC) matrix, wherein the LDPC matrix is derived from a base matrix, and wherein the base matrix is as follows: 35 71 56 55 — — 23 34 — — — 71 6 48 70 42 30 — 20 — — — 58 — 13 1 68 59 45 26 — — 55 — — — 74 2 61 30 — 34 — — 36 — 9 — 35 15 4 20 57 — 34 — — 79 — — 40 50 49 14 79 — 1 — — 12 65 — 46 78 78 46 — 40 — 80 17 — — 8 10 22 40 17 — 48 — 38 — 18 — 72 — 3 — 72 1 0 — — — — — — 14 — — 12 — 0 0 — — — — — 20 — — 20 — — 0 0 — — — — 50 — 46 — — — — 0 0 — — — — — 30 — 0 — — — 0 0 — — — — 20 — — — — — — 0 0 — — 6 — — — — — — — — 0 0 — 54 — — 1 — — — — — — 0.
