全数字OQPSK解调算法的研究及FPGA实现
论文介绍了OQPSK全数字接收解调原理和基于
软件无线电设计思想的全数字接收机的基本结构,详细阐述了当今OQPSK数字
解调中载波频率同步、载波相位同步、时钟同步和数据帧同步的一些常用算法,
并选择了相应算法构建了三种系统级的实现方案。通过MATLAB对解调方案的
仿真和性能分析,确定了FPGA中的系统实现方案。在此基础上,本文采用Verilog
HDL硬件描述语言在Altera公司的QuartusⅡ开发平台上设计了同步解调系统中
的各个模块,还对各模块和整个系统在ModelSim中进行了时序仿真验证,并对
设计中出现的问题进行了修正。最后,经过FPGA调试工具嵌入式逻辑分析仪
SignalTapⅡ的硬件实际测试,(The Research and FPGA Implement of All
Digital OQPSK Demodulation Algorithms

同步串行数据发送电路SSDT的基本功能是将并行数据转换成串行数据并进行同步发送。系统写入和读出时序完全兼容Intel8086时序。
系统以同步信号开始连续发送四个字节,在发送中出现5个1时插入一个0,在四个数据发送结束而下一次同步没有开始之前,发送7FH,这时中间不需要插入零
-synchronous serial data transmission circuit SSDT the basic function is to convert parallel data into serial and the same this step. System write and read sequential fully compatible Intel8086 timing. Synchronized signal system to start sending four consecutive bytes, in this emerging 5 1:00 insert a 0, at the end of four data sent and the next synchronization not started before, sending seven FH, then the middle is not inserted
