摘要
介绍了STANFORD和ZILOG公司联合研制的直接序列调制扩频芯片STEL - 2 0 0 0A(Z2 0 0 0 ) ,并提出了一种新型的基于该芯片并采用智能外围通信控制器Z80 182构成的电力线扩频数传终端方案 。
In this paper, we introduce a direct sequence spreading spectrum modulating chip STEL 2000 A. Then a scheme of power line spreading spectrum data transmission using Z80182 is proposed. Finally, the hardware construction and software design principle have been described.
