摘要：
In a cellular system using an OFDM scheme, a transmitter multiplies subcarriers for channel estimation by codes and transmits them, the codes being such that a phase difference φ of the code multiplied with consecutive subcarriers for channel estimation is constant, and a code of every M consecutive subcarriers (M being 2 or an integer greater than 2) is mutually orthogonal with a code multiplied with same subcarriers of another transmitter.
