提出一个新的双模盲均衡算法,这个算法在传统的双模恒模算法(DMCMA)的基础上引入维特比软判决器输出可信度信息。根据这个可信度.动态调整在DMCMA的两个模式之间切换的判决区域,进一步提高模式切换的准确性。仿真结果表明动态判决区域双模盲均衡算法的性能有较大的提高。
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.
