Abstract:
1. A transmission signal generation apparatus comprising: a mapper configured to generate a transmission signal, including a data frame having preamble information, pilot information, and data information, using either a first transmission signal generation method of generating a first transmission signal including a first pilot symbol sequence, a second pilot symbol sequence, and a first preamble multiplied by a factor so that an average reception power of the first preamble corresponds to an average reception power of the data information received with the first preamble, and a second transmission signal including a third pilot symbol sequence, a fourth pilot symbol sequence, and a second preamble multiplied by a factor so that an average reception power of the second preamble corresponds to an average reception power of data information received with the second preamble or a second transmission signal generation method of generating a third transmission signal including a fifth pilot symbol sequence, a sixth pilot symbol sequence, and a third preamble multiplied by a factor so that average reception power of the third preamble corresponds to an average reception power of data information received with the third preamble; and an Inverse Fourier transformer configured to: wherein: the Inverse Fourier transformer is configured to arrange:
