ABSTRACT:
A transmitting apparatus adds a common pilot symbol and known series for each data slot of a subcarrier group. A receiving apparatus combines SIR calculation values obtained for each subcarrier group, and averages the SIR calculation values. Based on this, it is possible to obtain a high-precision SIR calculation value even when there is a level fluctuation such as shadowing.
