We have an implementation of a UWB physical layer for ns-2 (see [1] 
below for more info) and we plan to port it and enhance it for ns-3 (and 
hopefully have it integrated). However, it is an implementation of an 
impulse-radio physical layer and not the multiband OFDM used in 802.15.3 
(which is by now dead, and is called WiMedia). But our implementation 
would be useful for 802.15.4a which is the alternate UWB physical layer 
for 802.15.4.

Best,
Ruben

This code is a modification and extension of ns-2 to support impulse 
radio UWB wireless networking. The two main components that are added to 
the plain ns-2 is the DCC-MAC layer (mac-ifcontrol.{cc,h}, DCC-MAC is 
our own MAC layer for UWB) and a model of an impulse radio UWB physical 
layer (interference-phy.{cc,h}) assuming time-hopping, pulse position 
modulation and convolutional code for channel coding (the BER is 
calculated with lookup tables that map the SNIR to the BER). We also add 
a propagation model for UWB channels.
