| 摘 要： | 连续相位调制(CPM)本身所具有的高功率和频谱利用率特性使得它在无线通信领域尤其是军事通信领域中应用广泛,但其解调的复杂度也随着部分响应长度和进制数的增加呈指数增长.文章给出了一种CPM的减少状态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.

| Abstract: | Continuous Phase Modulation(CPM) is widely used in wireless communications,especially in military communications,due to its high power and spectrum utility,but the complexity of its demodulation exponentially grows with the partial response length and the modulation parameters.This paper proposes a reduced-state noncoherent sequence detection algorithm for CPM,remarkably decreases the number of the matched filters by the orthogonalizing process,reduces the states of viterbi decoding by the state combination... |
