[14.] Chihi, H., Lacerda, R.D., Bouallegue, R.: Adaptive modulation and coding scheme for MB-OFDM
In this paper, we propose combined time synchronization and channel estimation suitable to work in harsh channel environment such as MB-OFDM
UWB systems channel models  in an attempt to enhance the MSE.
Other topics include body area networks for health monitoring, the MB-OFDM
ultra wide band system, receivers for short-distance wireless links, fractional PLLs for multiband synthesis, distributed effects in RF CMOS chips, and membrane-based MEMS systems.
Leveraging multiband OFDM (MB-OFDM
) technology, WiMedia UWB features the ability to control frequency band usage without requiring additional, costly software implementations.
The group's Multi-Band Orthogonal Frequency Division Multiplex (MB-OFDM
) specification describes a radio--the Common Radio Platform--that will operate on 128 bands inside 528-MHz frequency "blocks" in the UWB spectrum.
Proposed methods for implementing UWB solutions include time modulation UWB (TM-UWB), direct-sequence spread-spectrum impulse radio (DS-UWB), multi-band orthogonal frequency division multiplexing (MB-OFDM
) and multiband-impulse (MB-I) technologies.
