Abstract:
1. A transmitter comprising: a generator configured to generate a first sequence, a second sequence, a first block signal, and a second block signal, the first sequence being the same as a sequence obtained by performing a first cyclic shift on a CAZAC sequence, an amount of the first cyclic shift being a first amount, the second sequence being the same as a sequence obtained by performing a second cyclic shift on the CAZAC sequence, an amount of the second cyclic shift being a second amount different from the first amount, the first block signal being the same as a signal obtained by performing a third cyclic shift on a block signal, an amount of the third cyclic shift being a third amount, the second block signal being the same as a signal obtained by performing a fourth cyclic shift on the block signal an amount of the fourth cyclic shift being a fourth amount different from the third amount; wherein a period in which the first sequence and the second sequence are transmitted differs from a period in which the first block signal and the second block signal are transmitted; a gap between the first amount and the second amount differs from a gap between the third amount and the fourth amount; the first sequence and the first block signal are transmitted at least via a first antenna; and the second sequence and the second block signal are transmitted at least via a second antenna.
