不管是在民用通信还是军事通信,直接序列扩频的应用都非常广泛。文章简要介绍了直接序列扩频技术的发展,其中着重介绍的数字直接序列扩频接收技术是基于FPGA大规模可编程芯片的,并对该数字接收机模型进行了研究,最后给出了该数字接收机的实际测量数据。 Whether it is in civilian communications or military communications, direct sequence spread spectrum applications are very extensive. The article briefly introduces the development of direct sequence spread spectrum technology. The digital direct sequence spread spectrum receiving technology which is emphatically introduced is based on FPGA large-scale programmable chip, and the digital receiver model is studied. Finally, the figure Receiver actual measurement data.
