一种新的2CPFSK信号极化合成方法

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。

Polarization synthesis technique for 2CPFSK signal

A new polarization synthesis technique for continuous phase modulation signal is discussed. This technique is based on the multi-symbol noncoherent detection, and combines the demodulation with polarization synthesis together. In this 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 can be achieved.
