An interference eliminating circuit for removing an interference signal from a multi-carrier signal includes a training sequence generator, a first multiplier, a second multiplier, a phase shift circuit, a buffer, and an adder. The multi-carrier signal includes a first training sequence. The training sequence generator generates a second training sequence orthogonal to the first training sequence. The first multiplier attaches the second training sequence to the multi-carrier signal to obtain a new multi-carrier signal. The second multiplier attaches the second training sequence to the new multi-carrier signal to obtain the interference signal. The phase shift circuit shifts phase of the interference signal to obtain an adverse signal of the interference signal. The buffer buffers the multi-carrier signals. The adder adds the adverse signal of the interference signal to the buffered multi-carrier signals to remove the interference signal.
