为了提高快跳频多址系统的频谱利用率，引入了迭代干扰抵消技术。所提出的算法迭代地消除来自其符号已经被估计的用户的干扰。同时考虑了干扰信道和频率选择性衰落信道。采用非相干检测的M进制频移键控，并且所有用户在接收机处进行时间对准。分析结果和计算机模拟得到的结果。结果表明，迭代干扰消除可以大大降低误码率或允许同时发送用户的数量大幅增加。
Iterative interference cancellation is introduced to improve system spectral efficiency in fast frequency hopping multiple access systems. The proposed algorithm iteratively cancels interference from users whose symbols have already been estimated. Both an interference-only channel and a frequency selective fading channel are considered. Noncoherently detected M-ary frequency shift keying is employed and all users are time-aligned at the receiver. Analytical results and results obtained from computer simulations are presented. It is shown that iterative interference cancellation may either substantially reduce the bit error probability or allow for a large increase in the number of simultaneously transmitting users.
