1. A channel simulation method to simulate transmission on M×
- N channels formed by M transmission antennas and N reception antennas, comprising;
a channel variation forming step of forming a channel variation on each of the M×
N channels using information of arrangements of transmission and reception antennas; and
a channel variation adding step of adding channel variations corresponding to the M×
N channels to respective signals of the M×
N channels.

Abstract
Provided are switch 125 which makes N copies of each of M signals obtained in a transmission system, and thereby forms M×N channel signals, channel processing sections 126-1 to 126-MN which add correlated instantaneous variations and short-term variations corresponding to arrangements of transmission and reception antennas to the M×N channel signals, respectively, and selection combining section 128 which selectively combines M channel signals repeatedly among the M×N channel signals provided with channel variations to form N signals.
