摘要
本文介绍了CCSK扩频编码的应用及原理,阐述了应用FPGA进行解扩解调的实现方法。采用奇偶部分开发送的O-QPSK调制方式简化了FPGA实现的复杂度,同时具有不同码字间相关性小,并能在相同的信道带宽上传送更多的数据信息的特点。是一种CCSK扩频编码在FPGA上实现扩频接收的一种良好方法。
This paper introduces CCSK application and principle of spread spectrum coding, described despreading and demodulation method using FPGA. Using O-QPSK modulation of the odd and even some development delivery simplifies the complexity of FPGA implementation and correlation among different code words, and more data to be sent over the same channel bandwidth characteristics of the information. Is a CCSK spread spectrum coding on FPGA implementation of spread spectrum receiver in a good way.
