研究了一种采用多频码元进行固定时延编码的浅海多时频调制频移键控水声通信算法(MTFSK—Mutiple Time Frequency Shift Keying),并结合建立的浅海水声信道模型对算法进行了仿真研究。仿真结果表明:MTFSK算法性能稳定可靠,误码率小于10~(-4)。
A novel multi-frequency time-frequency modulated frequency-shift keying (MTFSK-Mutiple Time Frequency Shift Keying) scheme using multi-frequency symbols for fixed-delay coding was studied. The proposed algorithm was combined with the established shallow sea acoustic channel model simulation Research. The simulation results show that the performance of MTFSK algorithm is stable and reliable, the bit error rate is less than 10 ~ (-4).
