Abstract: | This letter introduces a novel pulse shaping scheme that enables receivers to demonstrate high performance in wireless fading environments. Called carrier interferometry pulse shaping, pulses are created by the superposition of N carriers. At the receiver, low probability-of-error performance is achieved by breaking the pulse into its frequency components and optimally recombining to create frequency diversity benefits. When implemented in a wireless TDMA system, simulations indicate 5-8-dB improvement at probability-of-error of 10 -2 over traditional Gaussian pulse shaping with decision feedback equalization (DFE(6,4)) in hilly terrain (HT) and typical urban (TU) channels |
