Abstract :
This paper provides a new spread spectrum signal detection in the presence of digital narrowband interference using nonlinear detectors by utilizing several moments in a frequency band. The proposed procedure amounts to a nonlinear processing on the received data and matched filtering. The performance assessments indicate that this receiver is able to suppress the effect of narrowband interference, which is assumed as an M-ary amplitude shift keying (ASK) signal. The new detector uses the information available in a bit duration of the spread spectrum signal and requires no training data.
