An interference cancellation module is provided to speedily and stably adapt to an initial channel by using FIR(Finite Impulse Response) filters together with a GLMS(Group Least Mean Square) algorithm and a GCMA(Group Constant Modulus Algorithm). An interference cancellation module comprises the first through fourth FIR filters(11-14). The first and second FIR filters(11,12) respectively are connected to the first and second determiners(21,22) and the first and second error function creation parts(31,32) in sequence. The third and fourth FIR filters(13,14) respectively are connected to the first and second squarers(71a,71b), the first and second subtracters(73a,73b), and the third and fourth error creation parts(33,34) in sequence. The first through fourth error function creation parts(31-34) are connected to a selector(40) and a multiplexer(80) in sequence, and the multiplexer(80) is connected to the first through fourth update coefficient parts(51-54).
