求翻译：现代方法有谱相关、小波分析、高阶累积量、粒子滤波等，这些方法在一定程度上提高对某些信号的检测能力，但存在算法复杂、适应信号类型单一等不足，且当接收到多个信号时性能恶化。是什么意思？

Modern methods of spectral correlation, wavelet analysis, cumulant, particle filtering, to some extent, these methods improve the detection of certain signals, but there is a complex algorithm to adapt the signal types such as lack of a single, and when receiving multiple signal deterioration.

Modern methods are relevant, Small wave spectrum, high-level cumulative volume analysis, particle filter, and so on, these methods to a certain extent, to raise certain signal detection capacity, but there are complex, adaptive algorithms such as a single signal types, and inadequate when it receive

The modern method has the spectrum to be connected, the wavelet analysis, the higher order cumulant, the granule filter and so on, these methods enhance to a certain extent to certain signal examination ability, but has the algorithm complex, the adaptation signal type sole and so on the insufficien

Modern spectral correlation analysis, wavelet, higher order cumulant and particle filtering, which raise some in part on signal detection capability, but insufficient algorithm for complex, adaptive signal type single exists and when multiple signals are received performance deterioration.
