In an interference cancellation apparatus for use in combination with a diversity receiving system, the apparatus includes first and second transversal filter means, first and second control means, third transversal filter means, third control means, decision means, first error producing means, and subtractor means which are operable as a first MMSE control loop for controlling first and second controllable tap gains and third controllable tap gains with reference to a first error signal. The apparatus further includes diversity combining means which are operable as a second MMSE control loop for controlling a combined signal with reference to a difference between the combined signal and a decision signal. An adaptive equalization and an interference cancellation are processed in parallel by the first and the second MMSE control loops, so that the control of the adaptive equalization and the interference cancellation can be converged at a high speed. <IMAGE> |
