    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 of the MIMO wireless communication, generating a carrier detect field, wherein, from transmit antenna to transmit antenna, the carrier detect field is cyclically shifted. The method continues by, for a first grouping of the transmit antennas of the MIMO wireless communication: generating a first guard interval following the carrier detect field; and generating at least one channel sounding field, wherein, from transmit antenna to transmit antenna in the first grouping, the at least one channel sounding field is cyclically shifted, and wherein the at least one channel sounding field follows the first guard interval. The method continues by, when the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas: generating at least one other channel sounding field, wherein, from transmit antenna to transmit antenna in the another grouping, the at least one other channel sounding field is cyclically shifted, and wherein the at least one other channel sounding field follows the at least one channel sounding field; and generating the first guard interval prior to the at least one other channel sounding field.

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: A programmable transmitter generates a frame preamble to train a receiver with respect to a communication link format that corresponds to a transmission mode wherein the transmission mode may comprise transmitting the communication link over one or more antennas. Generally, the invention includes generating a preamble with an arrangement that depends upon whether a Greenfield (high data rate) or mixed mode transmission is to occur and that depends upon a number of spatial streams that are to be generated. One format for high data rate transmission includes a short training sequence, a long training sequence and a signal field. The mixed mode transmission further includes a legacy prefix.

    摘要: An iterative decoder for use in a WLAN includes an inner decoder/detector, a first subtraction module, a deinterleaving module, an outer decoder, a second subtraction module, an interleaving module, and a determining module. The inner decoder/detector determines inner coded bits and extrinsic information of the inner coded bits from symbol vector based on a channel matrix and inner extrinsic information feedback. The first subtraction module subtracts the inner extrinsic information feedback from the extrinsic information of the inner coded bits. The deinterleaving module deinterleaves the output of the first subtraction module to produce deinterleaved inner extrinsic information. The outer decoder determines outer coded bits and extrinsic information of the outer coded bits from the deinterleaved inner extrinsic information. The second subtraction module subtracts the deinterleaved inner extrinsic information from the extrinsic information of the outer coded bits. The interleaving module interleaves the output of the second subtraction module to produce the inner extrinsic information feedback. The determining module produces decoded bits based on the outer coded bits.
