Abstract:
Disclosed is 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 4):
A signal reception apparatus comprising:\n reception circuitry that, in operation, receives control information indicating whether or not a precoding process that regularly changes phase has been executed with respect to a plurality of data reception signals; and decoding circuitry that, in operation, decodes the plurality of data reception signals based on the control information, wherein in a case of executing the precoding process, a signal transmission apparatus generates a first signal z 1  and a second signal z 2 , to be transmitted to the signal reception apparatus, by applying the precoding process on a first modulated signal s 1  and a second modulated signal s 2  by using a matrix selected from among 2 matrices F[i] for each of a plurality of slots to generate the first signal z 1  and the second signal z 2 , i being equal to an integer 0 and 1; and applying a transmission to the first signal z 1  and the second signal z 2  from a first antenna and a second antenna, respectively, wherein the 2 matrices F[i] is regularly hopping a phase change of \u03c0/2, each of the 2 matrices F[i] is selected at least once in 2 slots, the first signal z 1  and the second signal z 2  satisfy (z 1 , z 2 ) T =F[i] (s 1 , s 2 ) T , and the 2 matrices F[i] are expressed by the following equations: F \ue8a0 [ i ] = 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 ) ) \u03b8 21 \ue8a0 ( 0 ) = 0 , \u03b8 21 \ue8a0 ( 1 ) = \u03c0 2 .
