Abstract
An OFDM transmission apparatus performs transmission using an orthogonal frequency division multiplexing scheme in one or a plurality of frequency bands and includes a symbol multiplexing unit to multiply a column vector containing a first number of modulated symbols generated by primary modulation in a frequency domain, by a precoding matrix having as many rows and columns as the first number to generate a multiplexed symbol group containing the first number of multiplexed symbols each containing a second number of the modulated symbols that are multiplexed, where the first number is two or more, and the second number is equal to or more than two and equal to or less than the first number; and a subcarrier allocation unit to allocate the multiplexed symbols contained in the multiplexed symbol group to different subcarriers.
