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 8):
The broadcast signal reception apparatus according to  claim 7 , wherein\n the precoding satisfies the relation:\n ( z 1 , z 2) T =F ( s 1 , s 2) T  \n wherein z 1  and z 2  are signals after the precoding, s 1  and s 2  are signals before the precoding, (z 1 , z 2 ) is a row vector composed of the signals z 1  and z 2 , (z 1 , z 2 ) T  is a transpose vector of the row vector (z 1 , z 2 ), (s 1 , s 2 ) is a row vector composed of the signals s 1  and s 2 , (s 1 , s 2 ) T  is a transpose vector of the row vector (s 1 , s 2 ), and F(s 1 , s 2 ) T  is a matrix product of the determined matrix F and the transpose vector (s 1 , s 2 ) T .
