Abstract: Embodiments of an access point (AP), station (STA) and method for subcarrier scaling are generally described herein. The AP may transmit a high efficiency (HE) physical layer convergence procedure (PLCP) protocol data unit (PPDU) that includes a legacy long training field (L-LTF), a legacy signal (L-SIG) field, and an HE signal (HE-SIG) field. The HE-SIG may be based on HE-SIG symbols mapped to a group of HE subcarriers that includes legacy subcarriers and HE extension subcarriers. The L-LTF may be based on L-LTF pilot symbols mapped to the legacy subcarriers. The L-SIG may be based on L-SIG legacy symbols mapped to the legacy subcarriers and L-SIG extension pilot symbols mapped to the HE extension subcarriers. The AP may scale a per-subcarrier power of the L-SIG extension pilot symbols to match a per-subcarrier power of the L-LTF pilot symbols.

Abstract: A wireless device configured to process Multiple-Input Multiple-Output (MIMO) data streams. The wireless device includes a Singular Value Decompostion (SVD) engine configured to diagonalize a channel matrix into a precoding matrix; an SVD rotation engine configured to phase-rotate the precoding matrix, such that the channel matrix is partially de-diagnalized; and a transmitter configured to transmit a data packet corresponding to the phase-rotated precoding matrix.
