Abstract
Impulse radio ultra wideband (IR-UWB) communication is becoming an important
technology for future Wireless Personal Area Networks (WPANs). One of the critical
challenges in IR-UWB system design is the inter-pulse interference (IPI). A Transmit-reference
(TR) receiver is proposed to completely remove the IPI especially at low input frame energy-tonoise-
ratio (Ef/No) values. This receiver is based on the using of a modified version of
Hadamard matrix to yield a biorthogonal coded words instead of orthogonal ones. On the other
hand, from the complexity view, the proposed TR receiver in this paper has high complexity as
compared with the balanced coded orthogonal TR receiver proposed recently but it outperforms
it.
