Abstract:
1. A wireless communication device that performs communication using first to n-th main bands, the wireless communication device comprising: a data generating unit that generates broadcast data; a dividing unit that divides the broadcast data into m broadcast channels, a control unit that generates first to n-th amounts of shift to be provided to signals transmitted in the first to n-th main bands; n shift units, each shift unit outputting, in a corresponding main band, the m broadcast channels in an order of transmission of the m broadcast channels, the order for each shift unit being determined according to a respective one of the amounts of shift generated by the control unit; a placing unit that places the broadcast channels outputted from the shift units, on subcarriers in the first to n-th main bands; and a transmitting unit that converts the subcarriers in the first to n-th main bands into a transmit RF signal and transmits the transmit RF signal, the subcarriers having the broadcast channels placed thereon, wherein the control unit generates the amounts of shift such that the broadcast channels transmitted in corresponding frames of the different main bands are different and a difference between the first amount of shift and the second amount of shift differs from a difference between the second amount of shift and the third amount of shift, and a broadcast channel outputted according to the first amount of shift is placed on an (i−1)-th main band; a broadcast channel outputted according to the second amount of shift is placed on an i-th main band; and a broadcast channel outputted according to the third amount of shift is placed on an (i+1)-th main band.
