Abstract

Provided is a precoding method for generating, from a plurality of baseband signals, a plurality of precoded signals to be transmitted over the same frequency bandwidth at the same time, including the steps of selecting a matrix F[i] from among N matrices, which define precoding performed on the plurality of baseband signals, while switching between the N matrices, i being an integer from 0 to N−1, and N being an integer at least two, generating a first precoded signal z1 and a second precoded signal z2, generating a first encoded block and a second encoded block using a predetermined error correction block encoding method, generating a baseband signal with M symbols from the first encoded block and a baseband signal with M symbols the second encoded block, and precoding a combination of the generated baseband signals to generate a precoded signal having M slots.

First claim

The invention claimed is:

1. A transmission method comprising:
an encoding step of generating an encoded block using a predetermined error correction block encoding method;
a generation step of generating a first transmission signal z1 and a second transmission signal z2 by performing, for each of a plurality of slots, a precoding process on a first modulated signal s1 and a second modulated signal s2 that have been generated from the encoded block; and
a transmission step of…
