COMPRESSED OFDM SYMBOLS IN A WIRELESS COMMUNICATION SYSTEM

摘要

One or more first padding bits are added to information bits to be included in a data portion of a data unit such that the information bits, after being encoded, fill one or more OFDM symbols up to a boundary within a last OFDM symbol. The information bits and the first padding bits are encoded to generate coded bits. After encoding, coded bits corresponding to the last OFDM symbol are padded, or constellation points generated based on the coded bits corresponding to the last OFDM symbol are padded, such that the padded coded bits or the padded constellation points occupy a remaining portion of the last OFDM symbol after the boundary. The last OFDM symbol of the data portion is generated to include the coded information bits corresponding to the last OFDM symbol, the first padding bits and second padding bits or padding constellation points added after encoding.
