| Abstract(in English) | This paper proposes an ultra accurate carrier frequency control for OFDMA/TDD systems, in which two wireless stations can keep a very close carrier frequency with offset less than 0.01Hz in selective Rayleigh fading channels. In the proposed method, a wireless station corrects his carrier frequency using measured channel parameters in two directions. The carrier frequency can be corrcted accurately by use of channel parameters of subbands with good channel conditions. Furthermore, we proposes a novel phase control which aligns phases of the channel parameters accurately in two directions. The proposed method could be an enabling technology of coherent cooperative transmission from multiple stations towards low-power wireless communications. |
