Abstract
In this paper, we investigate the coexistence issue of two type of ultra-wideband (UWB) systems under IEEE 802.15.3a, i.e. Direct-Sequence UWB and MultiBand-Orthogonal Frequency Division Multiplexing UWB. The mutual interference of such coexistence scenarios is analyzed by physical layer Monte Carlo simulations. We observe severe and asymmetric performance degradation due to the mutual interference between the two systems. Therefore, we propose the goodput-oriented utility-based transmit power control (GUTPC) algorithm to improve the performance. The feasible condition and the convergence property of GUTPC are investigated, and the choice of the coefficients is discussed for fairness and efficiency. Numerical results demonstrate that GUTPC improves the goodput of the coexisting systems effectively and fairly.
