Due to the great evolution of high data rate applications in current wireless standard, energy efficiency (EE) is becoming an attractive metric that needs to be well investigated according to the increase of the consumed power. In this paper, we analyze the EE (bits/Joule/Hertz) of multiband orthogonal frequency division multiplex (MB-OFDM) system over IEEE 802.15.3a ultra wide band (UWB) channel...
In this contribution we study the challenging issue of WiMedia solution which the ability to support high data rate applications but is limited to three piconets simultaneously communicating in the same area. For this reason we analyze the suitability of Channel Division Multiple Access (ChDMA) approach for Multiband Orthogonal Frequency Division Multiplexing (MBOFDM) Ultra Wide Band (UWB) (MB-UWB)...
In this contribution, we study the performance analysis of the Multiband Orthogonal Frequency Division Multiplexing Ultra Wide Band (MBOFDM UWB) high data rate system. The major problem of the MBOFDM UWB high data rate system is the cohabitation of more than three piconets sharing the same group of subbands over the same channel. As an alternative way to enhance the spectral efficiency of MBOFDM UWB...
This contribution is focused on the design and analysis of an innovative multiple access scheme that exploits the intrinsic properties of the wireless environment to improve the multiuser environment, entitled Channel Division Multiple Access (ChDMA). Such a design allows simultaneous multiuser accessing to a common destination by considering the channel impulse response (CIR) of each user as a signature...
For Wireless Personal Area Network systems, the cooperation between different users and the coexistence of different piconets are very interesting points to take into consideration for the optimization of high data rate Ultra Wide Band systems. To improve the performance of the Multi Band OFDM, we investigate a new waveform obtained by the integration of an innovative scheme that exploits the user's...
