Abstract :
This paper analyzes multilevel pulse amplitude modulation (M-PAM) for energy detection receivers. Because of the asymmetric, non Gaussian probability density function (PDF) of the energy detected signal, the optimal signal constellation is not known a priori. In order to achieve optimal symbol error rate performance using M-PAM, the optimal signal constellation will be calculated. Finally the SER performance of the energy detection receiver based multiband impulse radio UWB architecture within the IEEE802.15.3 a channel model using M-PAM will be demonstrated.
