摘要： Methods and apparatus provide increased symbol length with more subcarriers in a fixed-bandwidth system. The subcarriers spacing may be reduced to provide increased symbol length and enable higher throughput. In one implementation, a system compatible with the IEEE P802.11n proposal can use 128 subcarriers in 20 MHz operation to provide increased throughput in lower-bandwidth channel operation.

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： Adaptive channelization is achieved in a high throughput multicarrier system by first subdividing a high throughput channel into a number of frequency sub-channels. A channelization decision may then be made within a device as to which of the sub-channels to use for a corresponding high throughput wireless link based on channel state information.
