Abstract:
1. A transmitter for use in an OFDM (Orthogonal Frequency Division Multiplexing) based mobile communication system, comprising: a transmission unit configured to transmit multiple symbols in a predefined time frame, the symbols including a guard interval part and an effective symbol part; and a setting unit configured to generate multiple sets of radio parameters used for transmissions from the transmission unit and broadcast for use in reception at a receiver, each of the sets of radio parameters specifying at least a subcarrier interval, a number of symbols in a single time frame and a period of the guard interval part, and to set any of the sets of radio parameters to the transmission unit, wherein at least two of the sets of radio parameters generated by the setting unit specify a common subcarrier interval and mutually different periods of the guard interval part and further specify mutually different numbers of symbols in a single time frame by one symbol such that a total period of the symbols in the single time is common.
