TS101信号处理系统上扩展实现水下通信编码器

Underwater Communication Encoder Expanded Solution Based on TS101S Embedded Signal Processing System

为了产生用于水声通信的各种信号,在已有信号处理系统软硬件限制的条件下,研制了一种基于DDWS方法实现的通信编码器,它能产生用于水下通信的连续不间断输出的任意信号,满足通信信号的精度和稳定性要求,OFDM信号的产生表明这种方法有效、可行,具有一定的通用性。

In order to generate the signal used in the underwater point to point communication, an encoder hardware based on DDWS in the case of limited hardware source is developed. The continuous complex signal wave used in underwater communication can be generated by this encoder hardware, and both the analog and digital signal can be outputted. The request of the precision and the stability of communication signal can be reached. The generation of OFDM signal shows that this method is simple and useful and is a universal way to generate signals.
