摘要:
连续相位调制的最佳检测方法为最大似然序列检测,传统的实现方法复杂度随着h的减小、L和M的增大而大幅度增加.该文给出了一种降低连续相位调制检测复杂度的方法,将Laurent次优检测与M算法相结合,从匹配滤波器的个数和状态网格图的状态数两方面简化系统,计算机仿真结果表明,在误比特率性能十分接近传统方法的情况下,CPM的检测复杂度得到了明显的降低.
Abstract:
The best method for detecting continuous phase modulation is the maximumlikelihood sequence detection. But its complexity will greatly increase with h decreasing and L and M increasing. Hence, we developed an improved method to lower the complexity in detection of continuous phase modulated signals. Combining the Laurent suboptimum detection and M algorithm, it reduced the detection complexity by matching the number of filers and the number of state trellis. Simulation was performed. The result demonstrated that, with a little degradation in BER, a remarkable receiver complexity reduction of CPM is achieved by using this method.
