Abstract :
This paper addresses the problem of adaptive modulation/demodulation scheme in the presence of interferences for wireless communication systems. We developed an adaptive modulation/demodulation scheme which modifies users´ signature waveforms by maximizing the signal to interference ratio based on wavelet packet analysis and the state-of-art interference avoidance algorithms.
