Performance Analysis of the Multiband Orthogonal Frequency Division Multiplexing Ultra-Wideband Systems for Multipath Fading and Multiuser Interference Channels

Table 2

Parameters of the UWB channel models.

Model parameters	CM1	CM2	CM3	CM4
[1/nsec] (cluster arrival rate)	0.0233	0.4	0.0667	0.0667
[1/nsec] (ray arrival rate)	2.5	0.5	2.1	2.1
(cluster decay factor)	7.1	5.5	14	24
(ray decay factor)	4.3	6.7	7.9	12
CM1 model is based on LOS (0–4 m) channel measurement.
CM2 model is based on NLOS (0–4 m) channel measurement.
CM3 model is based on NLOS (4–10 m) channel measurement.
CM4 model is generated to fit a 25 ns RMS delay spread to an extreme NLOS multipath channel.
