摘要
基于水声通信系统的需求,设计了基于FPGA的CDMA技术的调制/解调模块,选用m序列作扩频码,BPSK作为调制方式。该设计在EP3C10E144C8N芯片上,实现了各个功能模块,完成了CDMA调制/解调功能,仿真结果表明该设计功能正常并且工作稳定。CDMA调制/解调模块将应用于水声通信系统。
In order to meet the needs of underwater acoustic communication system,the modulation/ demodulation module of CDMA technology based on FPGA was designed. The m sequence is used as spread spectrum code and BPSK is taken as the modulation mode. Each functional module was achieved and CDMA modulation / demodulation function was completed on EP3C10e144c8n. The simulation results show that the system works properly and stably. The CDMA modulation / demodulation module will be applied to underwater acoustic communication system.
