Abstract:
1. A wireless communication device for use within a wireless communication environment, the wireless communication device comprising: a polarity setting module configured to set a polarity mode as one of a first polarity mode, a second polarity mode, or a dynamic polarity mode; a framing module configured to generate a data sub-frame for transmission, wherein the data sub-frame includes a channel estimation field that includes a first polarity portion and a second polarity portion; and an antenna module configured to transmit the first polarity portion in a first polarity, and the second polarity portion in a second polarity orthogonal to the first polarity, wherein, when the dynamic polarity mode is set, the framing module is configured to generate the data sub-frame such that first segments of the data sub-frame have the first polarity and second segments of the data sub-frame have the second polarity.
