Abstract:
A transmission scheme for transmitting a first modulated signal and a second modulated signal in the same frequency at the same time. According to the transmission scheme, a precoding weight multiplying unit multiplies a precoding weight by a baseband signal after a first mapping and a baseband signal after a second mapping and outputs the first modulated signal and the second modulated signal. In the precoding weight multiplying unit, precoding weights are regularly hopped.

Claim (Index 10):
A reception method for a wireless terminal apparatus comprising:\n receiving a control signal and a plurality of data reception signals transmitted from a wireless base station apparatus, the control signal indicating whether or not a precoding process is applied with respect to the plurality of data reception signals; and decoding the plurality of data reception signals based on the control signal, wherein in a case of executing the precoding process, a first transmission signal z 1 ( t ) and a second transmission signal z 2 ( t ), t being an integer equal to greater than 0 to be transmitted to the wireless terminal apparatus are generated by:\n applying a power adjustment to a first signal s 1 ( t ) and a second signal s 2 ( t ), \n applying the precoding process to the first signal s 1 ( t ) and the second signal s 2 ( t ) in accordance with Equation 4, and \n applying a transmission to the first transmission signal z 1 ( t ) and a second transmission signal z 2 ( t ) from different antennas at a same frequency and at a same time, wherein \n Equation 4 is expressible as: \n ( z \ue89e \ue89e 1 \ue89e ( t ) z \ue89e \ue89e 2 \ue89e ( t ) ) = 1 2 \ue89e ( e j \ue89e \ue89e 0 e j \ue89e \ue89e 0 e j \ue89e \ue89e \u03b8 21 \ue8a0 ( i ) e j \ue8a0 ( \u03b8 21 \ue8a0 ( i ) + \u03c0 ) ) \ue89e ( s \ue89e \ue89e 1 \ue89e ( t ) s \ue89e \ue89e 2 \ue89e ( t ) ) , and \u03b8 21 \ue8a0 ( 0 ) = 0 , \u03b8 21 \ue8a0 ( 1 ) = \u03c0 2 , where a variable i is an integer value that varies according to t, and \u03b8 21 (i) is a function with a variable i that is a set of 0 and 1.
