Blind Detection of Continuous Phase Modulation Signals with Integer and Half Integer Modulation Index

  • 摘要: 根據(jù)調(diào)制指數(shù)為整數(shù)和半整數(shù)的連續(xù)相位調(diào)制(CPM)信號(hào)的循環(huán)平穩(wěn)特性，該文提出一種在未知編碼序列、載頻、碼元寬度及峰值頻率偏移等參數(shù)的情況下對(duì)CPM信號(hào)的盲檢測(cè)方法。該方法是對(duì)傳統(tǒng)循環(huán)譜分析器的改進(jìn)。仿真實(shí)驗(yàn)證明該方法具有良好的檢測(cè)性能并容易實(shí)現(xiàn)，具有廣闊的工程應(yīng)用前景。
    Abstract: Based on the characteristics of cyclostationarity of Continuous Phase Modulation (CPM) signals with integer and half integer modulation index, a novel method of detecting CPM signals under the condition of unknown code sequence, carrier frequency, chip width and peak frequency deviation is presented in this paper. This method is an improvement of the traditional cyclic spectral analyzer; as well, its high detection performance is proved by the computer simulations.
