Diversity-multiplexing tradeoff of single-antenna and multi-antenna indoor ultra-wideband channels
In this paper, we study the achievable diversity-multiplexing gain (D-MG) tradeoffs over the IEEE 802.15.3a channel model. In particular, we give an exact expression of the D-MG tradeoff for single antenna systems. This expression is based on a statistical model of the integrated energy of the consi...

| Summary: | In this paper, we study the achievable diversity-multiplexing gain (D-MG) tradeoffs over the IEEE 802.15.3a channel model. In particular, we give an exact expression of the D-MG tradeoff for single antenna systems. This expression is based on a statistical model of the integrated energy of the considered channels. At a second time, we evaluate lower and upper bounds on the D-MG tradeoffs of multi-antenna systems. This formulation gives us more insights on the real potential of multi-antenna techniques with UWB systems. It is shown that even though the asymptotical diversity gain has an infinite value, the multi-antenna techniques can be very beneficial in the practical range of signal-to-noise ratios |
