Abstract

The coding performance of impulse radio ultra-wide bandwidth systems in the presence of multi-user interference is studied. Analytical expressions for assessing the codeword error probability and bit error probability are derived for soft-decision decoders in lognormal multipath fading UWB channels where the Rake receiver is used for signal detection. Numerical results are presented for different codes and error rate levels, and corresponding discussions of the coding performance characteristics in ultra-wide bandwidth systems are also provided.
