In this paper, Adaptive Symbol Skipping (AdSS) that is a collision avoidance scheme in multiband-OFDM (MB-OFDM) is evaluated. AdSS skips symbol transmission when a transmitter detects a signal from the other piconets. In the earlier work for AdSS, the probability of symbol loss has been analyzed in the case when no Time-Domain Spreading (TDS) is used. However, for the low data-rate modes of the MB-OFDM...
The multi-band orthogonal frequency division multiplexing (MB-OFDM) is an ultra wideband (UWB) technology that can transmit information at the maximum data rate of 480 Mb/s. When the simultaneous operating piconets (SOP) are located closely, the symbol collisions are expected to occur among the symbols transmitted over the same sub-band at the same time. This interference will decrease throughputs...
