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 1):
A broadcast signal generation method by a broadcast apparatus, comprising the steps of:\n applying a coding to a set of data bits to generate a first coded signal and a second coded signal; applying a precoding to the first coded signal and the second coded signal according to a determined matrix F; applying a phase change to the first coded signal and the second coded signal; and applying a pilot by inserting to the first coded signal and the second coded signal, wherein the first coded signal and the second coded signal with the phase change, the precoding and the pilot inserting applied are outputted to a plurality of transmission antennas to be transmitted on a same frequency band and at a same time as broadcast signals, the phase change is applied to the first coded signal and the second coded signal using a phase change value sequentially selected from among N phase change values, N being an integer greater than two and greater than the number of coded signals, and 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.
