ABSTRACT:
An Orthogonal Frequency Division Multiplexing (OFDM) signal having a symbol defining a transmission unit is produced by dividing data streams into a plurality of carriers within a predetermined bandwidth and prepared with orthogonal modulation. A transform unit having at least two systems transforms the received OFDM signal to a carrier domain signal per symbol unit. A composite circuit segments the carrier units and adaptively composites the signal data which constitutes a plurality of different carriers transformed by a first system transform circuit and the signal data which constitutes a plurality of different carriers transformed by a second system transform circuit for each identical carrier in each system.
