PROBLEM TO BE SOLVED: To provide a data transmitter and a data generation method, capable of discovering a device on a peer recognition wireless network which does not use a central control mechanism or communication infrastructure, while suppressing power consumption.SOLUTION: A resource block generation part for generating a resource block includes a symbol mapper for mapping a series of digital bits into a series of conjugate symbols, a serial to parallel conversion part, a subcarrier mapping part for allocating a user signal to each bandwidth, a N-point IFFT part, a parallel to serial conversion part, and a digital to analog converter for RF. A preamble generation part for generating a preamble includes a ZC sequence part for performing a ZC sequence, a second N-point IFFT part, a second parallel to serial conversion part, and a second digital to analog converter for RF. |
