Abstract  Abstract

To improve the precision of propagation path estimation in a case of receiving signals via a plurality of antennas. A transmitting apparatus at a base station end comprises a preamble A generating part (010); a preamble B generating part (011); phase rotating parts (012013); multiplex parts (014015); an error correction encoding parts (016); an S/P converting part (017); a mapping part (018); a switch (019); IDFT parts (020026) which may be substituted by IFFT parts; P/S converting parts (021027); GI (Guard Interval) inserting parts (022028); D/A converting parts (023029); radio transmitting parts (024030); and antenna parts (025031). The preamble A generating part (010) and preamble B generating part (011) generate preambles A and B respectively (See a packet format in Fig. 1). The preamble A is outputted to the multiplex parts (014015) while the preamble B is outputted to the phase rotating parts (012013). The phase rotating parts (012013) then apply a continuous phase rotation to each of the subcarriers of the preamble B. In a base station end transmitting apparatus according to the present embodiment not the phase rotating part (012) but only the phase rotating part (013) applies a phase rotation to the preamble B.
