Title:
TRANSMISSION APPARATUS AND TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/037546
Kind Code:
A1
Abstract:
An OFDM transmission apparatus (10a) that carries out transmission in one or more frequency bands through an orthogonal frequency division multiplexing system is provided with: a symbol multiplexing unit (300) that generates a multiplexed symbol group comprising a first number, which is not less than 2, of multiplexed symbols on which a second number, which is not less than 2 but not more than the first number, of modulated symbols are multiplexed, by multiplying a column vector in which the first number of modulated symbols obtained through performing primary-modulation in a frequency domain are included as elements, by a precoding matrix having the same number of rows and columns as the first number; and a sub-carrier arrangement unit (400) that arranges the multiplexed symbols included in the multiplexed symbol group in different sub-carriers.
