PROBLEM TO BE SOLVED: To reduce the generation rate of a diagonal solution and to attain exclusion of the possibility to be converged into erroneous solution by performing CMA-MMA blind type equalization, while using the non-object algorithm of a receiver composed of an adaptive filter having two filter configurations, including N pieces of tap coefficient vectors. SOLUTION: A digital signal processor 400 is provided with a processor 405 and a memory 410. One part of the memory 410 stores a program instruction for executing a coupled CMA-MMA algorithm at the time of execution due to the processor 405. The other part of the memory 412 is used for storing a tap count value to be updated by the processor 405. A received signal 404 is sent to the processor 405, and this processor 405 supplies an output signal 406 so as to equalize the signal in accordance with a concept. It is assumed that the output signal 406 expresses the sequence of output samples of an equalizer. |
