Spread spectrum-based white light communication with experiments

open access: yes, 2017
In this paper a Direct Sequence Spread Spectrum (DSSS) based offline wireless white light communication system is established. Field measurements are conducted to compare the performance with and without DSSS.

Performance analysis of direct-sequence spread-spectrum underwater acoustic communications based on at-sea data

open access: yes, 2019
Direct sequence spread spectrum (DSSS) signal uses phase coherent signals where the information symbols are multiplied with a code sequence, commonly known as chips. The signals are processed at the receiver using the code sequence as a matched filter to

A novel one shot object profilometry system using Direct Sequence Spread Spectrum profilometry

open access: yes, 2013
In this paper a new method of determining 3D object shape using patterns derived from Direct Sequence Spread Spectrum (DSSS) and an Unscented Kalman Filter (UKF) is presented.

DETECTION AND SYNCHRONIZATION OF DIRECT-SEQUENCE SPREAD-SPECTRUM SIGNALS

open access: yes, 2022
This thesis proposes strategies for both acquisition of direct-sequence spread-spectrum (DSSS) signals in high-dynamic environments, and noncooperative detection of DSSS signals. In particular, we propose delay-Doppler efficient exhaustive search (DEES),
