PROBLEM TO BE SOLVED: To provide a mobile object communication system, by which the accurate estimation processing of reception signal quality and proper data demodulation are realized. SOLUTION: A transmission side adds a common pilot symbol and a known sequence to the data slot unit of a subcarrier group. A reception side performs an averaging processing, after combining SIR calculation values obtained for subcarrier group units. Even in the case that the level fluctuation of shadowing or the like is present, the SIR calculation value is obtained accurately. |
