Abstract

The use of orthonormal scaling functions, wavelets and wavelet packets for modulation has recently been proposed. In this paper, we study the performance of different families of wavelets, for modulation over FDM nonlinear satellite channels, and we propose the use of a splitting technique to obtain two-channels modulation schemes with high spectral efficiency. Simulation results indicate that in certain cases the wavelet based shaping pulses could out-perform the traditional techniques in extremely critical transmission conditions, such as interchannel interference impaired satellite transmission
