电力线载波DSSS的ASIC研究与设计

Design and Study of ASIC on Communicating of PLC System Based on DSSS

电力线载波通信的特点采用扩展频谱通信方式,系统具有较强的抗干扰特性。通过FPGA运用ASIC的设计方法,对扩频通信的原理和实现过程都进行了论述,同时对于数字电表的SOC具有一定的意义。最后,利用已有的集中器产品,验证了系统原理。

According to attributes of PLC, the paper researches design of the PLC system on the DSSS theory. The PLC system is robust and discussed in detail and the implementation of PLC by the high-level design method is in the FPGA.Finally,the result make contributes to the development of digital power meter. The most advanced ASIC design technique is used in this research and it is described by VHDL. Finally, the theory verified on the relative devices .
