| 摘 要： | 针对基带PSK信号相位抗噪能力弱的特点,通过提高相位的直流分量,采用带通滤波和高阶差分的方法,在信噪比较低的情况下提取到信号的突变信息,实现了编码规律的恢复。理论分析了算法的实现过程,并进行了仿真试验,仿真结果表明,该算法在较低信噪下可以实现基带PSK信号的编码规律恢复。

| Abstract: | Aiming at the phase characteristic of baseband phase-coded signal having lower anti-noise ability,the transient information of signal is extracted by improving the DC component of phase and computing the high order difference of phase.In order to restore the phase shift keying rule at lower SNR,the original phase is corrected.The concrete method is analyzed in theory,and the simulation results show the method can analyze the intra-pulse feature of baseband phase-coded signal at lower SNR. |
