    摘要: 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.

    摘要: Briefly, a wireless communication system that may transmit and/or receive a data packet that may be generated by at least one of the wireless communication devices operated within the wireless communication system. The data packet may include at least one of a compatibility preamble field, a prefix training field, a physical layer convergence protocol header, a data field, a bit power load field and a postfix training field. At least some of the data packet fields may be encoded with a predetermined code and may be modulated by a predetermined modulation scheme.
