Abstract :
Wavelets are good decorrelators capable of separating signal from noise and have been used in denoising methods recently. Spread spectrum communication systems have been used for both military and commercial applications for many years. These systems have the ability to work in very low SNRs and are robust to intentional jamming. In such systems, noise cancellation can be very effective to improve performance. In this paper we propose a new denoising method in spread spectrum systems based on wavelet transform and compare it with general spread spectrum denoising methods
