Document Type and Number:
Japanese Patent JP4902663
Kind Code:
B2
Abstract:
A transmission apparatus divides transmission data according to spatial streams and transmits divided transmission data in parallel in an MIMO communication system. The transmission apparatus includes a control unit 8 that selects a modulation scheme for each of the spatial streams and determines a data allocation method for each of the spatial streams based on the modulation scheme; an allocating unit 3 that allocates the transmission data to each of the spatial streams based on the data allocation method determined by the control unit 8; and modulating units 4-1 to 4-N that respectively modulate allocation data for each of the spatial streams, which is an output from the allocating unit 3, by using the modulation scheme selected by the control unit for each of the spatial streams.
