摘要： All data symbols used in data transmission of a modulated signal are precoded by hopping 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 in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.

摘要： A transmission method includes encoding processing that generates an encoded block, modulation processing that generates symbols from the encoded block, phase change processing that changes the phase of the symbols, and transmission processing that arranges the symbols in data carriers and transmits the symbols. The transmission processing configures a frame by arranging symbol groups in order in the frequency direction and transmits the frame. The symbol groups each include a symbol generated from a first encoded block and a symbol generated from a second encoded block. The phase change processing includes changing the phase of symbols the same symbol group using the same phase change value.
