In this proposed new blind equalization algorithm, viterbi soft slicer output reliability information is imported based on conventional dual mode constant modulus algosrithm (DMCMA). According to this reliability information, the decision region between two modes in DMCMA is adjusted dynamically, and the shift accuracy of mode is further improved. The simulation results show that the performance of dynamic decision region dual mode constant modulus blind equalization algorithm is dynamically improved.
