Description: EXtrinsic Information Transfer (EXIT) charts are useful for characterizing the convergence properties and the performance of turbo receivers. Turbo receivers are generally constructed from two or more Soft Input Soft Output (SISO) modules. By simulating a single SISO module, the transfer characteristic of the SISO module can be obtained using the EXIT class. The transfer characteristics of two SISO modules represented on the same figure by switching the axes give the EXIT diagram. Platform: |

Description: 本文利用软输入软输出信道译码器输出对数似然比随相位偏差变化的规律得到低信噪比MPSK信号的
相位偏差代价函数，并提出一种求解该代价函数的迭代相位搜索方法，以相对较小的运算量实现较高精度的相
位估计。仿真表明，该算法在低信噪比下具有稳定的性能，并且能够克服大多相位估计算法都存在的相位模糊
问题。-In this paper, the soft input soft output channel decoder output log-likelihood ratio with the variation of the phase error signal to noise ratio MPSK signals with low phase error cost function and propose a cost function for solving the iterative phase of the search method relatively less computation to achieve high accuracy phase estimates. Simulation results show that the algorithm is stable under low signal to noise ratio performance, and most of the phase estimation algorithm can overcome the phase ambiguity exists. Platform: |
