| 摘要: |
| 针对低信噪比下连续相位调制信号的极化合成，提出了一种基于多符号检测技术的极
化合成新方法。通过把解调和极化合成作为一个整体进行处理，在基带上完成了通常在中频
上实现的极化合成过程，避免了连续相位调制信号在低信噪比下载波相位跟踪困难的问题。
仿真结果表明，该方法的合成效果与理论值之间的差距小于0.3 dB。 |

| Abstract: |
| A new polarization synthesis technique for continuous phase modulation
signal is discussed. This technique is based on the multi-symbol noncoherent det
ection, and combines the demodulation with polarization synthesis together. In t
his new technology, accurate phase tracking of weak continuous phase modulation
signal can be avoided. Simulation results show that less than 0.3dB gap between
test value and theoretical value c
an be achieved. |
