Abstract:
A transmission method simultaneously transmitting a first modulated signal and a second modulated signal at a common frequency performs precoding on both signals using a fixed precoding matrix and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.

Claim (Index 7):
A broadcast signal reception apparatus comprising:\n obtaining circuitry obtaining a reception signal, the reception signal being obtained by receiving a plurality of broadcast signals with a reception antenna, the plurality of broadcast signals being transmitted on a same frequency band and at a same time from a broadcast apparatus with a plurality of transmission antennas; and decoding circuitry decoding the reception signal, the decoded reception signal being outputted to a display, wherein the plurality of broadcast signals are generated by\n applying a coding to a set of data bits to generate a first coded signal and a second coded signal, \n applying a precoding to the first coded signal and the second coded signal according to a determined matrix F, \n applying a phase change to the first coded signal and the second coded signal, and \n applying a pilot by inserting to the first coded signal and the second coded signal, and \n wherein the phase change is applied to the first coded signal and the second coded signal using the sequentially selected phase change value, N being an integer greater than two and greater than the number of coded signals, each of the N phase change values being selected at least once within a determined period, and a difference between two adjacent phase change values of the N phase change values is 2\u03c0/N.
