Abstract :
A new multi-carrier CDMA system based on wavelet packets decomposition is introduced whereby the reduction of narrowband interference and pulse interference can be achieved. Using the adaptability of wavelet packets decomposition, a method called inverse mergence, which minimize the number of distorted time-frequency (T-F) units of the signal, is proposed. The expression of bit error rate of the system is derived and simulation results of the several decompositions of wavelets packets are presented
