Abstract
A mechanism of modulation in a more appropriate spatial domain is to be provided. A transmission device includes a signal processing unit that applies a precoding matrix on the basis of a first bit sequence to a complex signal point sequence converted from a second bit sequence, and the precoding matrix applied to the complex signal point sequence corresponds to the first bit sequence in a predetermined combination of a first bit sequence candidate and each element of a set of precoding matrices.
