1. A method for aligning high efficiency long training fields (“

  • HE-LTF”

    ) for data corresponding to a plurality of users, the method comprising;

    obtaining, at a wireless transmitter, data for transmission to a plurality of users via a plurality of wireless channels;

    determining a respective number of spatial streams corresponding to each user of a plurality of users for transmission via a data frame;

    determining a size for a template matrix based on a highest number of spatial streams of the respective numbers of spatial streams corresponding to each user of the plurality of users;

    accessing, from memory, the template matrix of the determined size;

    generating a respective matrix of HE-LTF symbols for each user of the plurality of users based on the template matrix, wherein each respective matrix comprises a number of columns that corresponds to the determined size, and wherein each respective matrix comprises a number of rows equivalent to the respective number of spatial streams;

    generating the data frame by aligning the matrices corresponding to the plurality of users in the data frame; and

    transmitting, via the wireless transmitter, the data frame via the plurality of wireless channels to the plurality of users.
