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 5):
A broadcast signal reception method comprising the steps of:\n obtaining a reception signal, the reception signal being obtained by receiving a plurality of transmission signals with a reception antenna, the plurality of transmission 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 the reception signal, the decoded reception signal being output to a display, wherein the transmission signals are generated by\n applying a coding to a first set of data bits to generate a first baseband signal and a second set of data bits to generate a second baseband signal, \n applying a phase change to the first baseband signal and the second baseband signal, and \n applying a precoding to the first baseband signal and the second baseband signal according to a determined matrix F, \n the phase change is continually applied to the first baseband signal and the second baseband signal using the sequentially selected phase change value, N being an integer greater than two and greater than the number of baseband 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.
