Transmission method and transmitter

Title:

Transmission method and transmitter

Document Type and Number:

Japanese Patent JP6365910

Kind Code:

B2

Abstract:

All data symbols used in data transmission of a modulated signal are precoded by switching between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol along the frequency axis and the time axis all differ. A modulated signal with such data symbols arranged therein is transmitted.
