摘要： A frame format provides for wideband wireless local area network communications and informs narrower-band communication units when the channels are occupied by wider-band communication units. In some embodiments, the frame format includes a channelization field identifying channels that are used for communicating subsequent wideband fields of a packet, and a wideband-header field communicated on the identified channels. The wideband-header field may identify sub-fields that may be present in the wideband-header field, and may identify the presence of a wideband-data field. A long-compatibility field may be present that provides protection at the MAC level. The long-compatibility field may transport MAC frames that may include medium-reservation information compatible with narrower-band communication units.

摘要： A quasi-parallel receiver may simultaneously receive signals within several subchannels that comprise a wideband channel. The receiver includes a subchannel filter selection switch that provides a baseband signal to a selected one of a plurality of subchannel low-pass filters. A heterodyne frequency generator provides one of a plurality of heterodyne frequencies to convert an RF signal received within a selected subchannel to the baseband signal. The subchannel low-pass filters accumulate signal information from an associated one of a plurality of subchannels during a filter-input sampling interval. In some embodiments, individual analog-to-digital converters receive the accumulated signal outputs from an associated subchannel filter and generate digital signals for a subsequent Fourier transformation. In some embodiments, a normalized signal output may be provided to the analog-to-digital converters, allowing the use of lower resolution analog-to-digital converters. The analog-to-digital converters may have sampling rates based on the subchannel bandwidth.
