1. An apparatus comprising:
a transmitter comprising logic and circuitry configured to generate a transmission of an Enhanced Directional Multi-Gigabit (DMG) (EDMG) Orthogonal Frequency Division Multiplexing (OFDM) Multi User (MU) Physical Layer (PHY) Protocol Data Unit (PPDU) for a plurality of users, the transmitter configured to generate a plurality of space-time stream flows corresponding to the plurality of users, respectively, a space-time stream flow corresponding to a user comprising one or more space-time streams corresponding to the user, wherein the transmitter is configured to encode the EDMG OFDM MU PPDU with an independent flow per user, and to maintain a common space-time stream numeration over all users of the plurality of users, the transmitter comprising:
a preamble builder to build symbols of an EDMG Short Training Field (EDMG-STF) and an EDMG Channel Estimation Field (EDMG-CEF) of the space-time stream flow corresponding to the user;
a scrambler to generate scrambled bits of the space-time stream flow corresponding to the user by scrambling bits of a data field for the user;
a Low-Density Parity-Check (LDPC) encoder to encode the scrambled bits of the space-time stream flow corresponding to the user into encoded bits of the space-time stream flow corresponding to the user according to an LDPC code;
a constellation mapper to map the encoded bits of the space-time stream flow corresponding to the user into constellation points over one or more spatial streams of the space-time stream flow corresponding to the user; and
a spatial mapper to map the plurality of space-time stream flows corresponding to the plurality of users to a plurality of transmit chains, wherein the one or more space-time streams corresponding to the user are based on the symbols of the EDMG-STF and EDMG-CEF of the space-time stream flow corresponding to the user, and on the constellation points over the one or more spatial streams of the space-time stream flow corresponding to the user.
