摘要： A method for generating a preamble of a frame for a multiple input multiple output (MIMO) wireless communication begins by, for each transmit antenna, generating a carrier detect field. The method continues by, for a first grouping of the transmit antennas, generating a first guard interval, and at least one channel sounding field. Continuing, the method applies cyclical shift prior to transmission via the first grouping of the transmit antennas. When the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas. For the another grouping of the transmit antennas, generating at least one other channel sounding field. The method proceeds by generating the first guard interval prior to the at least one other channel sounding field, and applying another cyclical shift prior to transmission via the another grouping of the transmit antennas.

摘要： A method for multiple protocol wireless communications begins by determining protocols of wireless communication devices within a proximal region. The method then continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by, when the protocols of the wireless communication devices within the proximal region are not of a like protocol, selecting a protocol of the protocols of the wireless communication devices within the proximal region based on a protocol ordering to produce a selected protocol. The method continues by utilizing the selected protocol by the wireless communication devices within the proximal region to set up a wireless communication within the proximal region.

摘要： The present invention provides a method for carrier detection associated with the receipt of MIMO RF packet communications. This involves receiving multiple MIMO RF packet communications with multiple receiver pathways, wherein the RF packet communications each comprise a preamble and data. The RF packet communications are sampled by a carrier detector before, during or after conversion to baseband. The carrier detectors are used to produce a set of carrier detection metrics for each reception pathway. These carrier detection metrics may be combined arithmetically with those of other reception pathways to produce a multi-reception pathway carrier detect. Alternatively, these carrier detection metrics can be processed to produce a logical decision or binary detection signal value associated with each reception pathway, which is then logically combined with the logical decisions of other reception pathways to produce a multi-reception pathway carrier detect.

摘要： Discriminating a modulation type based upon a predetermined portion of symbols for a received encoded signal. While receiving the encoded signal, at least a first and a second cumulative soft metrics are generated using the plurality of symbols over a predetermined portion of the received encoded signal. The first cumulative soft metric is compared with the second cumulative soft metric to generate or provide a discriminated modulation type. With the discriminated modulation type, the signal field is decoded, allowing for decoding of the accompanying data payload with the encoded signal.
