We present a method for coding speech signals for the simulation of a cochlear implant. The method is based on a wavelet packet\r\ndecomposition strategy. We used wavelet packet db4 for 7 levels, generated a series of channels with bandwidths exactly the same\r\nas nucleus device, and applied an input stimulus to each channel. The processed signal was then reconstructed and compared to\r\nthe original signal, which preserved the contents to a high percentage. Finally, performance of the wavelet packet decomposition\r\nin terms of computational complexity was compared to other commonly used strategies in cochlear implants. The results showed\r\nthe power of this method in processing of the input signal for implant users with less complexity than other methods, while\r\nmaintaining the contents of the input signal to a very good extent.
