The structure and performance on an orthogonal sinusoidal correlation receiver of impulse radio

Impulse radio (IR) is a competitive candidate for ultra-wide bandwidth (UWB) systems. A key feature of time-hopping IR is the subnanosecond pulses used to convey information. Analysis of such time-hopping schemes has been reported under a variety of assumptions. The performance of such IR systems is very sensitive to timing error, at least in part due to the very narrow pulses. A new structure of an orthogonal sinusoidal correlation receiver (OSCR) in IR systems is proposed to receive the subnanosecond pulses. Its tolerance to timing error is investigated. The receiver is proved to be efficient, practical and robust.
