Abstract :
Spread spectrum communication is suitable to work in very low SNRs, so noise cancellation can be effective to improve system performance for which we have considered wavelet denoising. In this paper we propose a new method in spread spectrum signal detection based on wavelet transform and compare it with general denoising methods for spread spectrum detection.
