Innovative pulse shaping for high-performance wireless TDMA

This letter introduces a novel pulse shaping scheme that enables receivers to demonstrate high performance in wireless fading environments. Called Car rier Interferometry pulse shaping, pulses are created by the superposition of N carriers. At the receiver, low probability-of-error performance is ach ieved by breaking the pulse into its frequency components and optimally rec ombining to create frequency diversity benefits. When implemented in a wire less TDMA system, simulations indicate 5-8-dB improvement at probability-of -error of 10(-2) over traditional Gaussian pulse shaping with decision feed back equalization (DFE(6,4)) in HT and TU channels.
