摘要

干扰建模困难是构建高效抗干扰探测器的主要问题之一。我们提出了一种利用信号相关结构来解释干扰的新型检测器。为了在两个复合假设之间做出决定，我们的检测器使用广义似然比检验。初步结果表明，该检测方案在强干扰情况下仍能达到较高的检测性能。

Interference-resistant detection based on time-frequency subspaces

The difficulty of modeling interference is one of the main problems in constructing an efficient interference-resistant detector. We present a new detector which exploits the signal correlation structure to account for interference. In order to make a decision between two composite hypotheses, our detector uses the generalized likelihood ratio test. Preliminary results suggest that the resulting detection scheme achieves high performance in presence of strong interference.
