  • OFDM RECEIVER AND METHODS FOR OPERATING IN HIGH-THROUGHPUT AND INCREASED RANGE MODES
    Publication number: 20100046671
    Abstract: An OFDM receiver operates in a high-throughput mode or an increased-range mode. The receiver includes FFT circuitry to generate frequency domain symbol-modulated subcarriers for a set of OFDM subcarriers. During the increased-range mode, data is received on a single subchannel and the FFT circuitry generates frequency domain symbol-modulated subcarriers for a set of OFDM subcarriers associated with the single subchannel. During the high-throughput mode, data is received on each subchannel of a plurality of subchannels and the FFT circuitry generates frequency domain symbol-modulated subcarriers for a different one of the subchannels. The OFDM receiver may operate in accordance with one of the IEEE 802.11 standards.
