| 摘 要： | MFSK/FFH系统特指采用快速跳频（FFH）技术和多进制频移键控（MFSK）非相干解调技术的系统,主要研究MFSK/FFH通信系统的多用户能力,并把它与差分跳频技术DFH的组网能力进行对比分析。通过分析MFSK/FFH通信系统的性能,给出了MFSK/FFH通信系统和差分跳频系统的比特差错率公式,为了公平对比MFSK/FFH网络和差分跳频网的组网能力,采用多用户频带利用率这个参数,理论和仿真表明,采用特定的检测方法,MFSK/FFH系统的多用户能力比差分跳频系统的好。

| Abstract: | The multiuser performance of multiple frequency shift keying/fast frequency hopping(MFSK/FFH) system,is discussed and compared with that of differential frequency hopping(DFH) system.Based on analysis of MFSK/FFH performance,the expression of MFSK/FFH Bit Error Rate(BER) is given.For fair comparison of MFSK/FFH networking and DFH networking,the multiuser efficiency for these two waveforms is adopted.The theoretical analysis and simulation results indicate that MFSK/FFH networking is better than DFH networki... |
