1) decimate conversion
抽取变换
3) UWPT
非抽取性小波包变换
1.
An shifted undecimated wavelet packet transform(SUWPT) excision algorithm is proposed for narrowband interference in DSSS communication system,which focuses the interference on one sub-band by frequency shifted,finds and removes it by energy compaction measure(EMC).
提出一种直接序列扩频系统(DSSS)中基于频移非抽取性小波包变换(SUWPT)的窄带干扰抑制算法,该算法在非抽取性小波包变换的基础上,利用频移将干扰更好的集中在某一子频段,并参考能量聚集度原则,对DSSS中的窄带干扰进行定位和抑制。
