  • Patent number: 7408998
    Abstract: A communication system includes a data transmitter and a data receiver in which the data transmitter transmits data using a multicarrier modulation, such as an OFDM modulation technique. The data receiver determines a predetermined level of modulation for at least one carrier of the multicarrier modulation corresponding to a received signal-to-noise ratio for the carrier using a vector quantization technique. The predetermined level of modulation for each carrier is based on an index to a codeword in a codebook corresponding to the signal-to-noise ratio for the carrier. The index to the codeword is a nearest neighbor to a vector corresponding to the signal-to-noise ratio for the carrier, and the codeword for each predetermined level of modulation is determined based on an adaptive-bit-loading technique. The data receiver transmits the index to the codeword for each carrier to the data transmitter in order to update the modulation at the data transmitter.
