Analysis of an Eigenstructure Technique for DSSS Synchronization
1997A new technique for synchronization of direct sequence spread spectrum (DSSS) signals is presented. This technique exploits the eigenstructure of a frequency-channelized DSSS signal to directly estimate the underlying spreading code. The synchronous estimate of the spreading code steadily improves with the increase in the collected data. In this paper,

A channelized DSSS ultra-wideband receiver
Proceedings RAWCON 2001. 2001 IEEE Radio and Wireless Conference (Cat.No.01EX514), 2002Critical to the design of a digital ultra-wideband (UWB) receiver is the ability for the analog-to-digital converter (ADC) to efficiently sample and digitize the UWB signal of several gigahertz. Designing a single ADC to operate at such frequencies is impractical, and parallel ADC architectures with each ADC operating at a fraction of the effective ...
