摘要
基于软件无线电思想,对二进制差分移相键控(2DPSK)信号解调原理进行了分析,利用Matlab对解调系统进行了设计和仿真。利用现场可编程门阵列(FPGA)对2DPSK信号差分相干解调进行了全数字化实现。该解调系统能够正确地恢复出原始基带调制信息,并且具有一定的升级空间。
Based on the idea of software radio, the two differential phase-shift keying (2DPSK) signal demodulation principle is analyzed and the relative demodulating system is designed using Matlab. The 2DPSK signal differential coherence demodulation is realized all-digitally by the field-programmable gate array(FPGA). The proposed demodulation system can recover the original baseband modulation informa- tion correctly, and has a certain upgrading space.
