Efficient channel estimation using Golay sequences

摘要

Certain aspects of the present disclosure provide an apparatus for wireless communication. The apparatus may generally include a processing system configured to generate a frame comprising a first sequence and a conjugate of the first sequence; and an interface configured to output the frame for transmission to a wireless node, wherein the first sequence and the conjugate of the first known sequence are simultaneously transmitted via first and second transmit chains. The first sequence maybe known by the wireless node prior to the transmission.
