Abstract
An OFDM system with ICI self-cancellation function comprises a first relay station, a second relay station and a receiver module. The first relay station comprises a first data sending/receiving unit, a first modulator connected with the first data sending unit, a first data configuration unit connected with the first modulator and a first inverse fast Fourier transform unit connected with the first data configuration unit. The first data sending unit is able to receive a first data source and send a first transmission data, the first modulator is able to receive the first transmission data and send a first symbol signal, the first data configuration unit enables the first symbol signal to be loaded in odd carriers, and the first inverse fast Fourier transform unit is able to transform the first symbol signal and comprises a first sending terminal capable of sending a first wireless transmission signal. The second relay station comprises a second data sending unit, a second modulator connected with the second data sending unit, a second data configuration unit connected with the second modulator and a second inverse fast Fourier transform unit connected with the second data configuration unit. The second data sending/receiving unit is able to receive a second data source and send a second transmission data, the second modulator is able to receive the second transmission data and send a second symbol signal, the second data configuration unit enables the second symbol signal to be loaded in even carriers, and the second inverse fast Fourier transform unit is able to transform the second symbol signal and comprises a second sending terminal capable of sending a second wireless transmission signal. The receiver module comprises an adder, a Fourier transform unit connected with the adder, a combining unit connected with the Fourier transform unit, a demodulator connected with the combining unit and a decision bit connected with the demodulator.
