| 摘 要： | 在基于时频编码抗衰落通信的基础上，把噪声编码通信技术运用到时频编码中，提出了采用随机的比特流实现多个PN码、多个频率、多个时隙的伪噪声时频编码的新途径，显著地提高了伪噪声时频编码信号抗干扰、低截获概率性能。在进行伪噪声时频编码信号设计的同时，给出信号性能详尽论述和数学分析，并通过计算机仿真验证了该方法的可行性和正确性。

| Abstract: | Based on the anti-fading communication of the TFSK(time frequency shift keying),a new method of using random bits to realize pseudo noise-TFSK with multi-PN code,multi-frequency and multi-time slot is proposed by applying noise coding technology into TFSK,so the anti-jamming(AJ)and low probability of intercept/detection(LPI/D) performance of the pseudo noise TFSK signal is improved remarkably.While designing this signal,the mathematic and theoretic analysis of the pseudo noise TFSK signal is presented,and the feasibility and correctness of this method is validated by simulation. |
