Title:
TRANSMISSION METHOD AND TRANSMITTER
Document Type and Number:
Japanese Patent JP2012195933
Kind Code:
A
Abstract:
To improve reception quality under an environment in which direct wave is dominant in a transmission method simultaneously transmitting a plurality of modulation signals from a plurality of antennae.
All data symbols used for data transmission of modulation signals to be transmitted are arranged in such a manner that a precoding matrix used for precoding of each data symbol is switched over to be different from precoding matrices used for precoding neighboring data symbols in a frequency axis direction and in a time axis direction, and then the modulation signals arranging data symbols are transmitted.
