ABSTRACT:
With the objective of making it possible to accurately estimate a transmission line and accurately demodulate a signal by a receiving device, the present invention provides a 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 a plurality of receiving antennas, wherein a pilot signal transmitted through the first transmitting antenna is made orthogonal to a pilot signal transmitted through the second transmitting antenna.
