Abstract  Abstract

PROBLEM TO BE SOLVED: To improve the precision of propagation path estimation when receiving signals from a plurality of antennas.

SOLUTION: A transmitting device on a base station side includes: a preamble A generating unit 010; a preamble B generating unit 011; phase rotating units 012 and 013; and multiplexing units 014 and 015. In the preamble A generating unit 010 and the preamble B generating unit 011 a preamble A and a preamble B are generated respectively. The preamble A is outputted to the multiplexing units 014 and 015 and the preamble B is outputted to the phase rotating units 012 and 013. In the phase rotating units 012 and 013 to which the preamble B has been inputted continuous phase rotation to respective subcarriers of the preamble B is given. In the phase rotating unit 012 phase rotation is not given and only in the phase rotating unit 013 phase rotation is given to the preamble B.
