通信信号的调制识别及调制参数特征值的估计是信号处理领域的一个重要研究方向。本文在改进遗传算法的基础上,首先确定最能表现信号调制差别的特征值集合,将该集合作为最优秀基因库,然后在遗传的演化过程中通过选择、交叉、淘汰引起的优秀基因库的变化,遗传过程中引入竞争惩罚策略引起基因库的优化,保证每代都是高质量的基因。
通信信號的調製識彆及調製參數特徵值的估計是信號處理領域的一箇重要研究方嚮。本文在改進遺傳算法的基礎上,首先確定最能錶現信號調製差彆的特徵值集閤,將該集閤作為最優秀基因庫,然後在遺傳的縯化過程中通過選擇、交扠、淘汰引起的優秀基因庫的變化,遺傳過程中引入競爭懲罰策略引起基因庫的優化,保證每代都是高質量的基因。

To estimate the characteristics of modulation identification and modulation parameters values is an important research direction in the ifeld of signal processing. Based on the improved genetic algorithm,the chapter ifrst determine the characteristics value assemble of the best performance of signal modulation diffenenrce, take it as the best gene pool,In the genetic process,the steps of selection,cross and elimination cause size change of excellent gene pool, cross, eliminated caused by the elite gene pools in the evolution of genetic, in the genetic process,adapt ing the strategy of competition and punishment to optimize the gene pool and ensure each generation are of high quality gene.
