<p>PROBLEM TO BE SOLVED: To provide a technology to determine channel characteristics of various communication systems such as OFDM systems or systems using a plurality of transmitting antennas. SOLUTION: In various embodiments, techniques are provided to determine channel characteristics of various communication systems such as OFDM systems or systems using a plurality of transmitting antennas by using various sets of training symbols for generating zero interrelation energy. Thus, the zero interrelation energy properly attains channel estimation without causing matrix inversion to simplify channel communication.</p> |
