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。
MFSK / FFH system especially refers to the system adopting fast frequency hopping (FFH) technology and multi-way frequency shift keying (MFSK) incoherent demodulation technology, and mainly studies the multi-user capability of the MFSK / FFH communication system and compares it with the difference Frequency hopping technology DFH network capacity comparative analysis. By analyzing the performance of MFSK / FFH communication system, the bit error rate formula of MFSK / FFH communication system and differential frequency hopping system is given. In order to fairly compare the networking capability of MFSK / FFH network and differential hopping network, multi-user frequency band Utilization of this parameter, theory and simulation show that MFSK / FFH system has better multi-user capability than differential frequency hopping system by using a specific detection method.
