Abstract:
1. A method comprising: determining, at a station, a number of available bits to be transmitted in a plurality of orthogonal frequency-division multiplexed (OFDM) symbols of a packet; determining, at the station, an integer number of low density parity check coded (LDPCC) codewords to be transmitted, and a length of the LDPCC codewords to be transmitted; determining a number of shortening bits per LDPCC codeword; encoding each of the available bits into the integer number of LDPCC codewords, wherein the shortening bits per LDPCC codeword are distributed to each of the integer number of LDPCC codewords; determining a number of bits for re-encoding the encoded LDPCC codewords; re-encoding the encoded LDPCC codewords based on the number of bits for re-encoding; and transmitting the re-encoded LDPCC codewords via the station.
