Patent ID: 8194777

Claim:
A method, comprising: receiving data bits for transmission; forward error correcting (FEC) the received data bits, wherein the data bits are coded using a Reed Solomon code then a convolutional code; interleaving the coded bits in a multicarrier communication channel according to a number of coded bits per Orthogonal Frequency Division Multiplexing (OFDM) symbol (N cbps ), wherein the interleaving is performed by: mapping adjacent coded bits onto non-adjacent subcarriers in the channel; then mapping the adjacent coded bits alternately onto less or more significant bits of a constellation to avoid long runs of low reliability bits, wherein a number of bits used is dependent upon a modulation type; introducing a guard interval to the interleaved and modulated coded bits to form an OFDM symbol; and transmitting the OFDM symbol in the multicarrier communication channel from two or more antennas.
