18. A method of transmitting data from a first communication deice to a second communication device, the method comprising:
generating a second number of mutually orthogonal sequences;
generating a third number of one or more spatial streams, each spatial stream carrying payload data;
splitting each of a first number of training symbols into a fourth number of tone sets, each training symbol spanning a plurality of tones;
splitting each orthogonal sequence into the fourth number of portions;
generating a training field by mapping elements of the corresponding portion of the orthogonal sequences onto the tone sets of the training symbols; and
arranging the training field before and/or between the payload data of the spatial streams to enable channel estimation by the second communication device.
