The performance of orthogonal pulse position modulation (PPM) and non-orthogonal
pulse position modulation (NPPM) is studied and compared with different ultra wideband
(UWB) channel models. Time hopping (TH) is used to decrease the effect of
interference in multi access environments. Rake receiver is studied as an ideal UWB
receiver for multiuser environments. It is shown that an ideal rake (I-Rake) receiver
has the best performance among all rake receivers, followed by 5 finger selective rake (5S-Rake), 5 finger partial rake (5P-Rake), 2 finger selective rake (2S-Rake), and 2 finger partial rake (2P-Rake). With a large number of users, NPPM can achieve a
better bit error rate (BER) performance than PPM. It is also shown that PPM and
NPPM in a triple Saleh-Valenzuela (TSV) channel has performance similar to that
in a Saleh-Valenzuela (SV) channel.
