ABSTRACT:
With the objective of reducing noise components to thereby avoid degradation of receiving characteristics, by making an antenna arrangement having taken into consideration transfer functions for radio wave propagation in an MIMO system, the present invention provides an OFDM transmission system suitable for use between a transmitting device that performs transmission using first and second transmitting antennas and a receiving device that performs reception using first and second receiving antennas, wherein the first transmitting antenna and the second transmitting antenna have an orthogonal relationship with each other and the first receiving antenna and the second receiving antenna have an orthogonal relationship with each other.
