OFDM is the obvious choice for use as a channel segmentation and collision avoidance framework for UWB. It would be nuts to consider CMDA imo. Seeing that UWB has come into conflict with entrenched spectrum users, the proponents needed an effective way to channel the use away from potential conflicts dynamically. They can also benefit from the superior multi path capabilities and better integration of MIMO and smart targetable array antenna technologies which will increasingly contribute to the effectiveness of wireless broadband over the next several years. OFDM/OFDMA also can serve as a more effective platform for hosting mesh and grid type networking and distributed layered architectures that may unfold even in a home electronics usage environment.

OFDM vs. CDMA for use in WBB of almost any description including UWB? No contest.
