Abstract

A transmitter comprises a transmit processor (105), preamble inserters (107, 109) and transmit units (113, 117) which are operable to transmit sub-signals from the antennas (115, 119). A preamble set comprising an individual preamble for each antenna generated by a preamble generator (111). Each of the individual preambles comprise first and second sections. The first section comprises a first data sequence, different for each antenna, and is selected from a predetermined set of preamble sequences. The first data sequence may comprise only time domain symbols belonging to the alphabet [1,-1, i,-i,0]. The second section comprises repetitions of a predetermined second data sequence where each repetition is weighted by a coefficient that is different for each antenna. Weighting may be by coefficients of different rows of a Walsh Hadamard matrix. The second data sequence may comprise only frequency domain symbols belonging to the alphabet of [1,-1,0].
