摘要
针对多进制相移键控(MPSK)类内信号,提出了一种以四阶累积量和差分星座最小环带模值方差作为特征的识别算法。通过仿真表明,信号长度为1600,信噪比为10 dB情况下,几种信号识别率达到100%。同时,该识别算法对载波剩余相位不敏感。
For the multiple phase shift keying(MPSK)signal series,this paper proposes a recognition algorithm featuring the fourth-order cumulant and the modulus variance of minimum ring with differential constellation.Simulation results show that the correct recognition rate can reach 100%when the length of symbols is 1600 and signal to noise rate is 10 dB.Meanwhile,and recognition algorithm is not sensitive to carrier residual phase.
