Analysis of an Eigenstructure Technique for DSSS Synchronization

1997
A 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,

Depression and Somatic Symptoms Scale (DSSS)

2011
The scale was developed as a simultaneous measure of depression and somatic symptoms – two issues that frequently co-occur [1]. Though many preexisting questionnaires for depression contain items relating to somatic complaints, the DSSS is specifically concerned with the relationship between the two.

A channelized DSSS ultra-wideband receiver

Proceedings RAWCON 2001. 2001 IEEE Radio and Wireless Conference (Cat.No.01EX514), 2002
Critical 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 ...

Driving safety support system: DSSS

Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat. No.99EX257), 2003
In order to decrease traffic accidents, we are developing driving safety support systems (DSSS), which prevents traffic accidents by providing information about danger and warning to drivers in advance. For example, when the traffic signals turn amber when approaching the intersection, a driver normally has to judge whether to pass it or stop in a ...
