Abstract :
Noise represents a major performance limiting factor for wireless communication systems. Pre-and post processing of the transmitted information enables to reduce the influence of noise significantly, leading to a severe performance gain. We apply the derivation of an optimal pre-and post processing to a single carrier system with frequency domain equalization (SC/FDE). Comparisons between the standard SC/FDE system with a zero-forcing equalizer and the enhanced system show a performance gain of up to 8 dB at a bit error rate of 10-5.
