To mitigate the problem of high peak to average power ratios in orthogonal frequency division multiplexing (OFDM) transmitters, an OFDM transmitter comprises division means (230) arranged in operation to divide a plurality of N sub-carriers into at least two blocks, and multicarrier modulation means operable to generate separate signals from said blocks of sub-carriers, for subsequent processing and transmission from respective antennas (291-294). |
