In awgn ( additive white gaussian noise ) channel , we introduce a new single - tone interference suppression scheme in the single - tone interference environment 针对加性白高斯噪声信道中的发射信号,提出了利用单音信号频域特性的单音干扰抑制方法。
According to the characteristics of single - tone in frequency domain , single - tone interference can be reconstructed . then interference cancellation is implemented 该方法结合单音信号在频域的特性,对单音干扰进行重建,然后通过干扰对消达到抑制干扰的目的。
There are several widely used methods to acquire the frequency response graph , including single tone method , multiple tone method , noise impulse method and maximum length sequence signal impulse method 分析音频设备的频率响应特性主要有单音信号检测法、噪声冲击检测法和最大长度序列检测法等。
Over multiple - path fading channel , a novel iterative single - tone interference suppression scheme is proposed for convolutionally coded system in the single - tone interference environment . the iterative receiver is based on the combination of iterative single carrier frequency domain equalization and interference rebuilding and cancellation 该方法利用衰落信道下单音信号的频域特性,对干扰信号进行重建及干扰抵消,同时,结合单载波频域均衡迭代检测技术,实现衰落信道中的联合单音干扰抑制及信号检测。
