摘要
基于DDS的原理及其调制特性,利用VHDL语言编程实现DDS。利用一组随机数的二进制编码的最高位作为控制生成BPSK信号的二进制码元。采用产生随机数的算法,并在此基础上进一步设计实现了一种基于DDS技术的BPSK信号,给出其主要部分的仿真结果,验证了其正确性。
Based on principles of DDS and VHDL language, use the highest digit of a group of random number＇s binary code to generate binary code element of BPSK signal; and adopt algorithm generating random number to generate BPSK signal based on DDS. Finally, some main simulation results are given, which validate its correctness.
