Abstract
A first communication device that is configured to transmit data to a second communication device comprises circuitry configured to generate a second number of mutually orthogonal sequences; generate a third number of one or more spatial streams, each spatial stream carrying payload data; split each of a first number of training symbols into a fourth number of tone sets, each training symbol spanning a plurality of tones; split each orthogonal sequence elements of the corresponding portion of the orthogonal sequences onto the tone sets of the training symbols; and arrange the training field before and/or between the payload data of the spatial streams to enable channel estimation by the second communication device.
