| 摘 要： | 对CPM系统中一种基于最大似然准则的维特比解调算法做了分析.并建立了CPM系统仿真模型,仿真结果表明,在误码率为10-4情况下,该方案性能比传统限幅鉴频技术提高约3 dB.最后在可编程逻辑器件开发环境QuartusII-9.0平台完成了整个算法FPGA设计,为工程实现提供了参考.

| Abstract: | Viterbi demodulation theory was introduced and analyzed .A CPM simulation mod-el was built using Matlab .The simulation results showed that when BER was 10 -4 , viterbi technique could improve the detection performance by 3 dB compared with the traditional de-modulation technique .The FPGA implementation were finished on Quartusll -9 .0 of Altera Company , which provided a reference model for the next step in realization . |
