Abstract :
We present an interference and noise analysis for multipulse multicarrier (MPMC) transmission over time-varying fading channels. Based on this analysis, we propose algorithms and guidelines for system optimization (transmit and receive pulse shapes, time-frequency lattice parameters, and power allocation). Numerical simulations illustrate the optimization gain and the superiority of MPMC systems over traditional (single-pulse) multicarrier systems for highly dispersive channels.
