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 pay load data; generate a fourth number of transmission training sequences, each comprising, in addition to a distinct orthogonal sequence of said mutually orthogonal sequences, one or more zeros and/or a subset of said distinct orthogonal sequence; generate a training field by mapping the transmission training sequences into a first number of training symbols, each training symbol spanning a plurality of tones; and arrange the training field before and/or between the payload of the spatial streams to enable channel estimation by the second communication device.
