    Abstract: Se realiza un proceso de precodificación en una primera señal de banda base y una segunda señal de banda base para generar una primera señal de precodificación y una segunda señal de precodificación. Una señal piloto se inserta en la primera señal de precodificación y el cambio de fase se realiza en la segunda señal de precodificación. Se inserta una señal piloto en la segunda señal de precodificación con cambio de fase, y el cambio de fase se realiza además en la segunda señal de precodificación con cambio de fase con la señal piloto insertada.

    Abstract: This transmitting device is provided with M (where M is an integer at least equal to 2) signal processing units which respectively generate modulated signals for M receiving devices, a multiplexing signal processing unit, and N (where N is an integer at least equal to 1) antenna units. When transmitting a plurality of streams, each of the M signal processing units generates two mapped signals, generates first and second precoded signals by subjecting the two mapped signals to precoding, periodically changes the phase of signal points in the IQ plane, with respect to the second precoded signal, and outputs the resulting phase-changed signal, and outputs the first precoded signal and the phase-changed signal as two modulated signals. When transmitting one stream, each of the M signal processing units outputs one modulated signal. The multiplexing signal processing unit multiplexes the modulated signals output from the M signal processing units, to generate N multiplexed signals. The N antenna units transmit each of the N multiplexed signals.

    Abstract: An encoding method of generating an encoded sequence by performing encoding of a given encoding rate based on a predetermined parity check matrix. The predetermined matrix is either a first parity check matrix or a second parity check matrix. The first parity check matrix corresponds to a low density parity check (LDPC) convolutional code that uses a plurality of parity check polynomials, and the second parity check matrix is generated by performing at least one of row permutation and column permutation on the first parity check matrix. A parity check polynomial satisfying zero of the LDPC convolutional code is expressible by using a specific mathematical expression.
