摘要： A method for processing a wireless signal includes performing by one or more processors, selecting a plurality of training sequences from a preamble of the wireless signal. Each of the selected plurality of training sequences may include a plurality of energy tones. The selected plurality of training sequences from the preamble may be shifted, in time domain, to generate a plurality of subsequent preambles for transmission. Each of the generated plurality of subsequent preambles may include the plurality of energy tones. The preamble may include a legacy preamble and/or an 802.11(n) preamble. The shifting in the time domain may include circular shifting. The circular shifting may include forward circular shifting and/or backwards circular shifting.

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.
