摘要 连续相位调制(CPM)与卷积编码相结合可以进一步提高系统的功率利用率,这使得它在无线通信领域中得到广泛应用。给出了卷积编码CPM的一种低复杂度的非相干序列检测算法,通过正交化处理有效地减少了匹配滤波器个数;在序列检测阶段通过状态融合减少维特比译码的状态数,然后结合判决反馈进行检测。 Combining continuous phase modulation(CPM)with convolutional code can further improve the power efficiency of the system,so it is widely used in wireless communications.This paper proposes a low-complexity noncoherent sequence detection algorithm for CPM combined with convolutional code.The number of matched filters is remarkably reduced by orthogonalizing process;and the states of Viterbi decoding are reduced with the state combination,and then the signal is detected with decision feedback.
