    • PURPOSE: An interference cancel system using a multiple path maximal ratio combining is provided to reduce computation steps by connecting an interference canceling terminal to the rearward of a multiple path combining terminal. CONSTITUTION: A multiple path treating terminal(10) has a rake receiving structure to reduce the influence of multiple path fading. A multiple path combining terminal(20) combines the multiple path signal(ZK,L) by a maximal ratio combining(MRC) method or equal gain combining method so as to reduce the number of signals. An interference canceling terminal(30) cancels the interference of signal(Sk) which is combined in the multiple path combining terminal. Finally, a multiple user determining terminal(40) determines the signal of the multiple user from the signal(dk) whose interference is cancelled in the interference canceling terminal. Since the interference canceling terminal is connected to the rearward of the multiple path combining terminal, the signal is reduced in number in the multiple path combining terminal and is input to the interference canceling terminal, the computation steps in the interference canceling terminal is decreased.
