Abstract

M-ary bi-orthogonal modulation or M-ary bi-orthogonal keying (MBOK) is a modulation scheme that has recently been considered for use in several consumer wireless standards, including the IEEE 802.11 WLAN standard and the ultra wideband (UWB) 802.15.3a WPAN standard. In this paper, we propose a novel blind adaptive equalizer for such signals. We then discuss the relation of the algorithm to other blind algorithms and demonstrate its local convergence. Finally, we present some numerical examples that demonstrate its features and performance.
