摘    要:针对希尔伯特黄变换(HHT)能够给出非平稳信号的瞬时频率的特点,提出了HHT调制解调方式。通过RAKE接收和RS纠错编码技术相结合,建立起HHT水声通信系统;并对HHT水声通信系统进行系统仿真,通过仿真的误码率曲线分析了HHT水声通信系统的性能。最后经过湖试,试验数据表明HHT水声通信系统在实际通信环境中是稳定的、有效的,HHT应用于水声通信系统中是可行的。

关 键 词:希尔伯特黄变换  水声通信  RS编码  RAKE接收机

Abstract:According to the characteristics that the instantaneous frequency of non-stationary signal can be given by Hilbert-Huang Transform(HHT) method,HHT modem method is proposed.Combining with Reed-Solomon(RS) code and RAKE receivers,the HHT underwater acoustic communication system was built.The performance of HHT underwater acoustic communication system was analyzed through system simulation and bit error rate(BER) curves.The results of the Lotus lake test data show that HHT underwater acoustic communication system in the actual communication environment is steady and valid.HHT method has been used in underwater acoustic communication system that is feasible.
Keywords:Hilbert-Huang Transform(HHT)  underwater acoustic communication  RS code  RAKE receivers
