1. A radio communication device that switches a frequency channel to be used by using a predetermined hopping pattern during communication with a counterpart radio communication device, the radio communication device comprising:
a null determination circuitry to determine a position of a null symbol included in a received packet from the counterpart radio communication device;
an interference measuring circuitry to measure an interference amount by using the null symbol included in the received packet; and
a timing control circuitry to calculate a control amount of transmission timing for transmitting a transmission packet to the counterpart radio communication device on the basis of the interference amount, wherein
the received packet includes modulated symbols to which a modulated signal and the null symbol are mapped by frequency mapping,
the interference measuring circuitry measures an interference amount for each of the modulated symbols constituting one received packet, and
the timing control circuitry calculates a correction value for each of the modulated symbols on the basis of the interference amount for each of the modulated symbols and a maximum value of interference amounts held in advance, and calculates the control amount on the basis of the correction value for each of the modulated symbols.
