Document Type and Number:
Japanese Patent JP7137357
Kind Code:
B2
Abstract:
To provide a transmitter, a receiver, and a chip, capable of achieving hierarchical transmission in an OFDM transmission system using a plurality of transmission systems.SOLUTION: In a transmitter transmitting an OFDM modulation signal using a plurality of transmission systems, a transmission band of a transmission signal has a segment structure, hierarchical transmission is performed, and a space division multiplexing MIMO transmission system or a space-time coding MISO transmission system is selected for each hierarchy. In the transmitter, interleaving between hierarchies is performed, and the interleaving between hierarchies selects interleaving in carrier unit and interleaving in segment unit, on the basis of a transmission system for each hierarchy and the number of data carriers for respective segments.SELECTED DRAWING: Figure 1
