| Abstract: | 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. |
